Cloud computing offers an ideal solution for reducing costs, time, and complexity in data management, but data security remains a critical concern. This study proposes a novel approach that combines partial homomorphic encryption (PHE) with digital watermarking to improve the authenticity and integrity of data in cloud environments. Our method employs a chaotic map for key generation, ensuring unique and non-duplicate keys, and utilizes the One-Time Pad (OTP) principle with probabilistic encryption for data protection. The watermarking technique, based on linear interpolation, enables tampering detection without compromising data privacy. We implement this approach using a symmetric linear scheme to achieve homomorphic properties, allowing specific operations on encrypted data without decryption. Experimental results demonstrate that our method achieves lower computational complexity compared to
