Image retrieval scheme with object detection and quantised colour histogram
Yuvaraj Tankala and Joseph K Paul, 5th-semester B Tech Computer Science and Engineering students of SRM University-AP, Andhra Pradesh, India has worked with Dr Manikandan V M, Assistant Professor in Computer Science and Engineering Department on a research project and their research paper “A Content-based Image Retrieval Scheme with Object Detection and Quantized Color Histogram” got accepted for publication in the International Journal of Computational Science and Engineering.
Content-based image retrieval (CBIR) is an active area of research due to its wide applications. Most of the existing CBIR schemes are concentrated to do the searching of the images based on the texture, colour, or shape features extracted from the query image. In this manuscript, we propose an object detection based CBIR scheme with quantized colour histograms. In the proposed scheme, the meaningful objects will be identified from the query image by using you only look once (YOLO) object detection techniques and the quantized histograms of each of the object categories. The object lists, their count, and the area covered by the objects along with quantized colour histograms will be used during feature matching to retrieve the related images from the large image pool. The experimental of the proposed scheme is carried on the Corel 1K and Caltech image dataset. We have observed an average precision of 0.96 during the experimental study which is quite high while comparing the precision from the well-known existing schemes.
To retrieve relevant images from a large image pool, we use content-based image retrieval (CBIR) schemes. In a CBIR scheme, the properties of the query image will be matched with the properties of the images in the image pool. The images which are very close to the given query image will be returned by the CBIR scheme. Most of the existing CBIR schemes use colour, shape and texture properties for image comparison. In the proposed scheme, we use an object detection-based approach with quantized colour histograms to retrieve the relevant images from the image pool.
The real-life applications of the proposed scheme are listed below:
● In the fashion designing and textile industry, CBIR systems can be used to find the existing designs.
● The CBIR systems are useful in crime prevention by retrieving similar crime scenes or the images of criminal persons based on the query image.
● Professional web designers or poster designers want to retrieve relevant images depends on the specific context that they are working.
● To retrieve similar medical images with the relevant treatment details in a computer-assisted diagnosis system.
The team currently continue their research work in the same domain to come up with a content-based image retrieval system that will return the relevant images by understanding the relationships among the objects in the image. The classes of the objects in the scene and their properties also will be considered along with the relationship between the objects in the scene.

Securing Online Payments made through Wearable Devices
Smart devices and Internet of Things (IoT) are growing in importance every day and so do our security concerns about using them for our financial transactions. As we carry the world with us through wearable technology, Dr Sriramulu Bojjagani, Assistant Professor, Department of Computer Science Engineering works towards making wearable devices more secure.
With a thriving interest in Cyber Security, Formal Verification Methods and Vulnerability Analysis and Penetration Testing, Dr Bojjagani has recently published his paper on “A Secure IoT-based Micro-payment Protocol for Wearable Devices” in Peer-to-Peer Networking and Applications (PPNA), Springer.DOI: 10.1007/s12083-021-01242-y
Abstract:
Wearable devices are one of the parts of the essential cost of goods sold (COGS) in the wheel of the Internet of things (IoT), contributing towards a potential impact in the finance and banking sectors. There is a need for lightweight cryptography mechanisms for IoT devices because these are resource constraints. This paper introduces a novel approach to an IoT-based micro-payment protocol in a wearable device’s environment. This payment model uses “elliptic curve integrated encryption scheme (ECIES)” for encryption and decryption of the communicating messages between various entities. The proposed protocol allows the customer to buy the goods using a wearable device and send the mobile application’s confidential payment information. The application creates a secure session between the customer, banks, and merchant. The static security analysis and informal security methods indicate that the proposed protocol is withstanding the various security vulnerabilities involved in mobile payments. For logical verification of the correctness of security properties using the formal way of “Burrows-Abadi-Needham (BAN)” logic confirms the proposed protocol’s accuracy. The practical simulation and validation using the Scyther and Tamarin tool ensure the absence of security attacks in our scheme. Finally, the performance analysis based on cryptography features and computational overhead of related approaches specify that the proposed micro-payment protocol for wearable devices is secure and efficient.
Architecture for wearable devices:
The architecture for wearable devices is shown in Fig. 1. It consists of six types of entities, such as Issuer bank (IB), acquirer bank (AB), payment gateway (PG), a certification authority (CA), mobile terminal, and wearable sensing devices. The person using various wearable devices such as a smartwatch, smart wristband, smart glass, etc. In the architecture, a wearable device is connected to the mobile terminal through NFC. An app is running on a mobile device. Wearable devices are resource constraints because they have limited computing capabilities regarding battery, display, storage, and processing compared to a mobile terminal (smartphone). Hence, NFC is used to pair the wearable device and mobile terminal for transmitting public messages. Before conducting any transaction with the merchant, the customer and merchant should register their mobile numbers with the bank.
Fig. 1. Architecture for wearable devices
The customer can place an order with the merchant using the following steps and the complete messages flow in the proposed protocol is shown shown in the Figure.
● The customer places an order for an item through a wearable device.
● The request is transferred to the mobile app. The mobile app verifies the user authentication.
● After a successful authentication request, the app forwarded the request to the issuing bank for payment verification.
● The customer also sends a payment request for a deduction of the amount from his/her issuing bank.
● Once the bank validates the customer data in terms of sufficient funds available and user’s integrity. The issuing bank routes the transaction to the payment gateway through a secure network.
● In this step, the payment gateway verified the customer payment order and transferred it to the acquiring bank.
● If all the verifications are successful, then the transaction amount is then debited from the issuing bank and credited to the merchants’ acquiring bank.
Application demonstration:
As we know, most wearable devices run the Android operating system. The proposed framework developed as an Android application package (APK) file run in an Android wearable emulator, but we have operated in the Samsung Galaxy Note-2 device due to limits of the screen device and lack of environment. First, it needs to install the APK file and start running the app. Before running the app, some points need to be considered, such as the following:
● The company voice gateway provided for the service of an SMS gateway connected to Xeon server and assigned us a shortcode 56677.
● The payment gateway switch is used to communicate with the customer and merchant bank accounts.
● Two mobile numbers are registered with the banks and telecom operations, and it is used for SMS service.
● The deployed decryption web application on the Xeon server.
● HTTPS connection is used between voice gateway and Xeon server established Indian financial network (INFINET) link between server and bank.
We have not mentioned all the screenshots for the app from starting the login and authentication phase, but the protocol requires the essential information only shown in the screenshot. We didn’t mention the banks considered for implementing the micro-payment protocol for security and reputation reasons.
The proposed protocol action is as follows:
Step 1: The customer x runs a wearable application to enter Wearable-id, mobile number, pin and amount and sends an encrypted message to the Xeon server via short-code 56677. To encrypt the message, the customer may choose any one of the ECC curves as shown in Fig. 2.
Step 2: The SMS gateway receives the encrypted SMS, which is delivered to the server
Step 3: The server receives the encrypted SMS and executes the decryption application. Next, the user runs decryption activity and selects the P-224 private key. After decryption, the message is shown in Fig. 3.
Step 4: After the message is decrypted, the user presses the “Next” button to communicate with the payment gateway.
Step 5: Now, the merchant fills in the remaining fields of merchant UPI-id, mobile number, and purpose of payment and then selects any payment gateway as shown in Fig. 4.
Fig. 4: The merchant enters the details and sends to any payment server
Dr Bojjagani’s research will further refine the parameters of security in IoT enabling wearable devices to become smarter and safer.
- To make the proposed protocols more secure can add biometric-based authentication can be added.
- The future directions of the proposed framework fit only for micro-payments. In future, we have upgraded to credit card/debit card payments to enhance the proposed framework for macro-payments.

The faculty members and mentors are always ready to clear our doubts and continuously help us to improve our performance by conducting mock interviews by industry experts, group discussion sessions, etc… They encouraged us when we are in low spirits. SRM AP has done a great job in bringing many reputed companies such as Amazon, Paypal, Barclays, etc… for placement drive. All along the way my family and faculty have supported me in this stressful yet fruitful journey of placement drive. I would like to take this chance to thank SRM AP Management, the CR&CS department, Faculty and mentors for giving me the chance to fulfil my dream.
Nanduri Geeta Kiranmai
When I came to know that I received an offer in Optum UHG as a software engineer, it was like my dream come true moment. I am very happy that I got an opportunity to enter into a well-established company at the beginning of my professional career. I used to do a lot of coding on data structures and algorithms from my second year itself. The sessions taught by CCC and their regular practice links as Homeworks brushed up my fundamental concepts in programming. I used to maintain handwritten notes on all the core subjects in my bachelors, which helped me to revise the concepts a day before the interview. I was able to mention all the projects that I have mentioned in my resume.
One of the most important aspects of being an SRMite is a high standard curriculum which helped me in acquiring knowledge in all kinds of domains related to CSE. The curriculum made me establish a strong foundation that is required for industries at present.
The efforts of the Placements Department is not only appreciated by me but also by my family for their dedicated work towards all the students who enrolled in placement. Superset portal made the process of the recruitment drive simple and easy, the Opportunities provided by the Placements Department are so great that all the students get placed in dream jobs! The placement team came up with their online sessions for clearing the doubts of the students regarding the placements weekly which helped us a lot in this pandemic even though we didn’t have offline classes the process of placements went on smoothly.
I suggest to my juniors to get prepared with projects from the beginning itself so get ready for the placement by the starting of the fourth year with a good resume. I advise the students to pick a coding platform of their choice and do regular practice on it so that they develop logical and problem-solving skills
Sadhvika Nalluri
I am really happy about the offer at Optum because it was my first interview and I got placed right at that. I could perform well for theoretical questions in programming languages in which I am good in and also the coding part. I brushed through the concepts of OOPS, C, C++, DBMS and my academic projects. Most of the questions they asked in the interview were already in the curriculum and our faculty rally helped us a lot while studying and also clarified our doubts. The academic projects we have done were so much useful in the interview.
The CR&CS department gave us special classes to go through the concepts of major subjects that are required to crack the job. They also provided special classes in association with training institutes on communication skills and interview skills. They will respond to us immediately if there is an issue either in the interview or while writing the exam.
My message to juniors is that before I got this offer, I was rejected by so many companies without even qualifying prelims. There were some days when I got an invitation for the interview but could not attend as there was no invite link in the email. But I did not lose hope. So have patience and wait for your chance.
Sourish Mukherjee
This job offer from Optum is a dream come true for me. I can’t be happier since this is everything I expected from my first job. As soon as saw the job offer on our portal, I started to prepare for my logic and technical assessment. The coursework provided by CDC was very helpful and the domain training lessons provided by the college helped me do well in the assessments. After I received a call for the technical interview, I immediately started focusing on my projects and started brushing up on my technical knowledge based on my resume. The guidance of the esteemed faculty of SRM University-AP is a vital reason for my success. I thank them for building my resume and for all the knowledge they imparted to us, despite remotely working due to the pandemic. I consulted with my teammates and friends as well and as a result of all this and determination, I have been able to crack the final HR interview.
The mock interviews conducted by the CR&CS department helped me refine my answers and my personality as a suitable candidate. My father also helped me immensely to prepare for my interviews. I thank the CR&CS department for choosing reputed companies and giving me a chance to apply for this job opening and for ensuring the process is as smooth as possible. I would like to share a few words for my juniors and peers. Everyone will get a chance to prove themselves and reach their goal. Never lose hope and keep striving for your goals. Don’t feel sad if you get rejected. I was rejected by almost 30 companies but what I learnt in the process was to treat it as another stepping stone, an experience and an opportunity to get better and grab better opportunities that will come my way. I would like to wish the very best for all my peers and juniors, success in their professional and educational endeavours.
Tirumani Someswari Sai Rushitha
I’m very happy and excited as I could secure the super dream offer and I’m looking forward to proving my skills as a contributing member of the Organization. During the recruitment drives the guidance by the placement department was indeed helpful like the domain, technical training, and also the company-specific exams which assisted me to prepare accordingly.

Obtaining encrypted images with new Reversible Data Hiding scheme
SRM University-AP is pleased to announce that Dr V M Manikandan, Assistant Professor in the Department of Computer Science and Engineering, along with his research scholar Shaiju Panchikkil, published a paper titled, “A convolutional neural network model based reversible data hiding scheme in encrypted images with block-wise Arnold transform” in Optik Journal, Elsevier Publications.
The proposed scheme can be used for embedding electronic patient reports (EPR) in the medical image itself while transmitting, and at the receiver side the reports can be extracted along with the lossless recovery of the medical images.
About the Research:
Data hiding or information hiding is a well-explored way to secure some secret data by concealing it in a digital cover medium. The reversible data hiding (RDH) is a recent advancement in the field of data hiding in which the cover medium can be restored during the extraction of hidden messages at the receiver side. The RDH schemes are widely used in medical image transmission and cloud computing. Recently, research in the field of RDH in encrypted images got much attention to improve the efficiency parameters such as embedding rate and bit error rate without compromising the lossless recovery of the images. In this research paper, we propose a new RDH scheme in encrypted images which utilizes the Arnold scrambling technique for data hiding. A convolutional neural network (CNN) model is trained and used to extract the hidden message along with the recovery of the original image. The experimental study and result analysis of the proposed scheme are carried out on the USC-SIPI image dataset managed by the University of Southern California.
Dr Manikandan collaborated with Prof. Yu-Dong Zhang, Professor in School of Computing and Mathematical Sciences, University of Leicester, UK collaborated for this research work. In the future, Dr Manikandan’s research will be more focussed on coming up with new reversible data hiding schemes in encrypted images with better embedding rate and bit error.

CSE student wins Best Paper award and cash prize in International conference
Padmaja Buggaveeti, an outstanding student from 3rd-year Computer Science Engineering at SRM University-AP, has won Best Paper (Third Prize) and a cash prize of Rs 10000 /- (Ten thousand rupees only) at the 4th ISEA Virtual International Conference on Security and Privacy 2021. Ms Padmaja, under the mentorship of her guide Dr V M Manikandan, presented a paper titled “A Novel Prediction Error Histogram Shifting-based Reversible Data Hiding Scheme for Medical Image Transmission” at the International Conference on Security and Privacy, sponsored by Information Security and Education Awareness Project Phase-II (ISEA-II) and organised by IIT (ISM) Dhanbad, India from October 27-30, 2021.
Abstract: In this paper, Ms Padmaja proposed a new prediction error histogram shifting-based reversible data hiding scheme that ensures a high embedding rate and lossless image recovery. The pixels in the images are categorised into two different classes: white pixels and black pixels based on a checkerboard pattern. To predict the black pixel value for finding the prediction, they used the average of three pixels out of 4-neighbourhood pixels, which are very close to the central pixel value. The prediction error histogram is considered for further data hiding through the histogram shifting approach. An efficient overflow handling technique is used for this. The proposed algorithms were implemented using Matlab-2020, and the experimental study of the proposed scheme is carried out on the standard medical images and natural images.
International Conference on Security and Privacy is a premier conference focused on information security and privacy. This year’s conference was sponsored by Information security and Education Awareness Project Phase-II (ISEA-II) and organised by IIT (ISM) Dhanbad, India, from October 27-30, 2021.
Prize Details: Best Paper (Third Prize) and a cash prize of Rs. 10000 /- (Ten thousand rupees only).
Let’s hear what Ms Padmaja says about her achievement!
I thank Dr V M Manikandan, Assistant Professor in the Department of Computer Science and Engineering, for his valuable guidance in this research work.

Efficient algorithms for dualisation problem for subclasses of Boolean functions
SERB-DST projects aim to build up the best systems that would match the best global practices in the area of promotion and funding of basic research. Dr Murali Krishna Enduri, Assistant Professor, Department of Computer Science Engineering at SRM University-AP is yet another faculty member who has obtained a project with a total outlay of ₹18 lacs for a duration of three years. The project is sanctioned under the scheme of Teachers Associateship for Research Excellence (TARE) of SERB-DST, Government of India.
In the duality theory, the dual problem is the problem of checking the duality of a pair of monotone Boolean expressions in disjunctive normal form. Problem: DUAL Input: The complete DNF of two monotone Boolean functions, f and g. Output: If f is dual of g. Whether the problem DUAL admits a polynomial-time algorithm has been one of the challenging open problems in the field of Duality theory of Boolean function for the last 35 years. It is one of the few problems whose polynomial-time solvability is still unknown. So, this problem is important in complexity theory due to its unknown complexity status and it plays a central role in various applications arising in computational logic, data mining, reliability theory, artificial intelligence and game theory etc. The project goal is to solve the dual problem for an interesting class of Boolean functions. Improving the existing complexity results of the DUAL problem for a particular class of Boolean functions is a challenging task.
Few applications of the project are as follows:
Type error diagnosis: Type error diagnosis is the task of generating an explanation for some error. It requires finding all minimal unsatisfiable subsets of a given set of constraints (representing the error) which can be managed via solving the computational variant of Dual in its minimal transversal formulation.
Computational medicine: Optimal vaccination strategies are given a subset of initially infected individuals from a population of individuals and assumptions about disease transmission. The task of computing inclusion minimal vaccination strategies can be solved using the computational variant of Dual in its transversal hypergraph formulation.
The project will be carried out in collaboration with IIT Madras (Dr Jayalal Sarma, Associate Professor, Department of Computer Science & Engineering, Indian Institute of Technology Madras, Chennai, India.)
