Review On Prevention of Data Leakage in Cloud Server by Utilizing Watermarking and Double Encryption Techniques

In today's world, the exchange of multimedia data has become an essential part of people's everyday routines, as they utilize various systems, services, and applications. Real-world cloud storage systems frequently experience data leaks, making secure data transmission and copyright protection of multimedia information difficult. To tackle the problem of safeguarding copyright, the implementation of digital watermarking has been proposed. This technique involves adding hidden information, such as confidential data, to digital media to authenticate its ownership. Encryption techniques are also employed to secure the data and prevent unauthorized access. The proposed approach suggests using both watermarking and proxy re-encryption techniques to efficiently exchange multimedia content. To secure confidential information, the process involves encrypting a private key with a specific encryption method that requires a key. Next, this encrypted key is combined with the user's private key and inserted into an image using the Least Significant Bit (LSB) technique. After the confidential information has been incorporated into the image, it can be encoded using the ECC Encryption technique. However, copyright protection remains a challenging and complex issue in the face of increasing internet and digital technology usage. The resulting image can be encoded using the ECC Encryption method.
