Preventing Data Leakage in Cloud Servers through Watermarking and Encryption Techniques

Abstract

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.

A Hybrid Double Encryption Approach for Enhanced Cloud Data Security in Post-Quantum Cryptography

“…Since security is the primary concern in cloud computing, some users may find themselves comfortable transmitting information via the cloud. Cloud computing specialists have created certain secret keys for account security and use encryption methods to safeguard cloud servers [2,3,5]. To safeguard the data from threatening attacks, specific encryption techniques might be employed.…”

“…A shield against security issues that have frequently prevented the cloud from functioning and growing effectively is created by combining these techniques. Data security in the cloud utilizes a sophisticated strategy that combines innovative technology, widely accepted practices, and stringent regulations to safeguard data from unauthorized access, data breaches [5], and other cyber consequences of these challenges. One such cryptographic method combines NTRU Encrypt and AES encryption, resulting in an effective Double Encryption method.…”
