Abstract
<span>Cloud computing has introduced substantial advancements to the field of information technology, offering businesses enhanced features, flexibility, reliability, scalability, and a wide range of services. However, it also presents security challenges like data theft and manipulation. To minimize the risks associated with these threats, a model that depends on encryption and steganography is proposed with the aim of applying a security model in a cloud environment. The proposed cloud security model utilizes a multi-layer model that includes a Rivest-Shamir-Adleman (RSA), advanced encryption standard (AES), identity-based encryption (IBE) methods, least significant bit (LSB) method, and the Brotli method. This comprehensive approach effectively safeguards data integrity, confidentiality, and privacy against potential intruders. In addition, it enhances the flexibility and efficiency of the cloud by enabling the secure storage and transmission of large amounts of data.</span>
