The development in the cloud computing technologies and the information security policy, the data recovery from the hidden technologies is improved and also it is most implemented methodology. The recovered data from the embedded can also be error free and the redundancy is very low even though it was encrypted using different available encryption algorithms. The traditional algorithms embed the data and recover using the dame approach. We proposed encryption algorithm using Least Significant Bit (LSB) and Auxiliary syndrome Encryption Standard (AES). In this approach, we first create an auxiliary syndrome for the data using AES algorithm and then embed the data in the least bit extracted using the wavelets of the cover image. The message is inserted into the first sub-image of the cipher picture after image encoding and encryption, and each pixel can load a bit of secret message. The embedded data can be effectively retrieved and the original picture can be correctly restored on the receiver side utilizing the encryption key and extracted auxiliary syndrome. The proposed method gave the best analysis in terms of Peak Signal to Noise Ratio (PSNR) and Bit Error Rate (BER).
