The wavelet algorithms are applying the high level of image/data compression by using transforms. The main processes of wavelets are allowing some complex information such as images and videos to be decomposed into elementary forms. These processes are applied at different positions and balancesto rebuild with high precision. Signal transmission depends on the transmission of a progression of numbers. The series portrayal of capacity is significant in a wide range of sign transmission. The wavelet portrayal of capacity is another strategy. Wavelet change of a volume is the improved variant of Fourier transform. This chapter discusses more on applying an encryption standard by modifying the Discrete Wavelet Domain (DWT). In this work, the performance of modified DWT image encryption algorithms is measured and equated using the computation time. The entropy of the process determined the Randomness and provides how secure the image is encrypted. In this paper, we approach this issue by building up a scientific model for obviously scrambled pictures and afterward determine expectations and differences of NPCR and UACI metrics. Further, these hypothetical qualities are utilized to frame measurable theory NPCR and UACI tests. Basic estimations of tests will help in predicting an encryption standard. Thus, the topic of whether a given NPCR/UACI score is adequately high to such an extent that it isn't noticeable from ideally encoded pictures is replied by observing at real NPCR/UACI scores with comparing basic qualities. Test results utilizing the NPCR and UACI irregularity tests will determine the existing encryption techniques are really equivalent or not
