Secure Watermarking to Protect Colour Images on Social Media from Misuse
Privacy and Secure Revocable Data Access Control in Multi-Authority Cloud Storage

Access control service provided by cloud is used for giving protection against unauthorized access to data.Ciphertext-Policy Attribute-Based Encryption (CP-ABE) is mostly considered for data access control in cloud storage. The existing CP-ABE is difficult to apply in multi-authority cloud storage due to the attribute revocation problem. The proposed revocable multi-authority CP-ABE scheme provides solution to the attribute revocation problem. The proposed scheme updates the components of the revoked attribute only and generates latest secret keys for the revoked attribute and forwards it to the non revoked users who have the attributes as revoked attributes. The Backward security and Forward security is maintained. If the revoked user enters into the system again by doing the registration process means, the particular user is identified via the identity card detail in the revocation list and they ar...

Hadoop performance however is significantly affected by the settings of the Hadoop configuration parameters. Unfortunately, manually tuning these parameters is very time-consuming. Existing system uses Random forest approach, which automatically tune the Hadoop configuration parameters for optimized performance for a given application running on a given cluster. Random forest approach try every combination of configuration parameter values and choose the best one. Unfortunately, this is unrealistic because of the huge number of Hadoop configuration parameter combinations. This takes a considerable amount of time, leading to impractically long times. In the proposed system we consider the constraints in the resource allocation process in the MapReduce programming model for large-scale data processing for speed u...

Every individual is sharing his/her activities like photos, message, etc. through social media (i.e. WhatsApp, Facebook, etc.) to other persons without authentication of all these data and through this general activity of people some people are doing fraud to them or misuse of these data or illegally showing to other people without his concern. To ensure the authentication of digital contents this paper proposes methodology to prove the ownership by Digital watermarking and Intellectual Property Right (IPR). This paper explains the concepts of IPR and proposed alphanumeric watermarking technique for authentication of images and its protection from the fraud or misuse. Digital Watermarking has become one of the research areas in many fields from more than decades. This paper gives the methodology of embedding and extraction techniques for images to prove the authentication o...

Smart phone and internet are two main resources which are being used by persons most of the time in his/her daily routine specially in lockdown due to COVID-19. In this lockdown, persons are doing some creative activity, making fun, etc and recording all his/her this personal information in the form of multimedia contents like text, images, audio and video. This created multimedia content is shared by persons frequently on globe through internet in the daily routine life and some other persons are watching this daily routine activity and making huge business with these data by sometimes with original content or sometimes with modified content without concerns/information/permission of the originator. In this process if everything is going in right way then no issues but if something going wrong then require legal issues and for this, we ne...

The proposed system dynamically engages candidates by asking follow-up questions, interpreting their responses, and providing personalized feedback. Unlike conventional chatbots with fixed question flows, this model enables bi-directional communication-allowing candidates to both answer and ask questions-thereby closely mirroring genuine interview environments. Leveraging modern NLP technologies, the system generates context-aware interview questions based on industry standards and user preferences.
