Cloud computing has become a key technology for storing and processing data, but it also introduces major security concerns such as data privacy, integrity, and unauthorized access. This paper presents a lightweight and effective data protection approach that combines multi-layer data transformation techniques with blockchain technology to improve cloud security. In the proposed method, user credentials are first merged with a secret key and then processed through several stages including binary conversion, two’s complement calculation, octal encoding, and reverse sequencing to produce encrypted data. In contrast to conventional cryptographic methods like AES (Advanced Encryption Standard) and RSA (Rivest–Shamir–Adleman), the proposed technique emphasizes lower computational complexity while still providing an acceptable level of security. Furthermore, the use of blockchain technology guarantees data immutability and integrity, protecting the information from unauthorized modification. Experimental analysis shows that the method offers faster execution and efficient performance, making it appropriate for real-time cloud-based applications. The findings indicate a balance between security capability and computational efficiency, suggesting that the proposed approach can function as an additional security layer in cloud computing environments.
