Integrity Protection of Text Document Data from Unauthorized Modifications
Abstract: Digital watermarking provides authentication, validation and copyright protection for multimedia contents over the internet. Text is the most widely used means of communication in addition to image, audio and video. So it needs to be protected. Text watermarking techniques that have been developed in the past protects the text from illegal copying, imitation, and prevents copyright violations. In this paper, we have proposed an algorithm that ensures the integrity and …

Password Protected Image Encryption and Decryption using Hybrid Technique for Data Security
Abstract: Abstract: Data security and data anti-corruption are some areas of cryptography which is under continuous research and development. In this paper, a password based protection scheme has been included in order to increase the level of security of data. Here a hybrid technique for data security has been proposed and compared with its non-hybrid counterparts which resulted in the hybrid technique giving better results for various parameters of study like …

Digital Image Authentication on Cloud using QR Code
Abstract: In these days, many people are using social sites for sharing and uploading their life moments as images. And other users can capture or even download those digital images. Hacker can edit and modifying the original image and make a duplicate image. Modify images can then be uploading and sharing. This research generally discusses the importance of QR with Digital Watermarking. The QR Code based Digital Watermarking is possible in …

Navigating the Dual Edge: A Comprehensive Technical Survey of Security, Privacy, and Countermeasures in the Era of Artificial Intelligence
Abstract: Artificial intelligence (AI) is seamlessly woven into vital sectors, such as self-driving cars, high-speed trading systems, and defense strategies; it has triggered a counterintuitive development in advanced cyberattacks. This survey paper attempts to perform an in-depth technical analysis of the “AI attack surface.” There are threats across three main vectors. Data integrity attacks focus specifically on examining “clean-label” poisoning and backdoor injection. Model confidentiality breaches discuss the mathematics behind model …

Speech Hiding in a Digital Image using DWT and DES Algorithm
Abstract: AbstractThe proposed paper presents a speech hiding technique in a digital image (DI). Here the technique used is Discrete Wavelet Transform (DWT). It secures speech signal from unauthorized users. It can be done by embedding speech into an image by steganography. Thus, unauthorized users will not detect secret speech in stego image. Suppose unauthorized users detect the speech that will be fraud because no one can obtain speech signal without …

Enrichment of Storage Capacity of QR Codes Using Colored Approach
Abstract: Copyright protection and authentication is increasing and becoming important in daily life. The digitized watermark is one of the techniques invented to solve this issue. Maximum storage capacity of QR code with the use of only two colors i.e. black and white is maximum up to 4296 characters in version 40. This capacity of QR can be further enhanced by the utilization of more colors with black and white, which …
