Due to the increasing utilization of various systems, services, and applications, sharing multimedia data has become a vital component of individuals' daily routines. However, data leakage is a common problem in cloud storage systems, which poses a significant threat to the confidentiality and copyright protection of multimedia information. To address this issue, digital watermarking has been suggested as an effective method for protecting copyright. The recommended approach combines watermarking and Proxy Re- (PRE) to ensure secure multimedia material exchange. Encryption techniques are also used to protect data from unauthorized access. The proposed method includes encrypting a secret key with a certain key, then combining it with encrypted key data, and ultimately embedding it into an image via the Least Significant Bit (LSB) technique. Once the sensitive information is inserted, the image can be encoded using the ECC Encryption method.Built-in data to the verification method allows authenticated individuals to recover the decryption key, which can identify unauthorized access and restrict content redistribution. The proposed application has the potential to prevent unauthorized access in cloud environments and ensure the security of sharing multimedia data.
