“…In PBS, limiting the signer's signature permission and not restricting the verifier's permission is more secure in privacy-preserving than ABS. PCS was proposed by Pairat et al [1], [2] in 2017. A signer can sign a message and attach it with some policies.…”

“…We analyze the performance of the proposed PCS-PP scheme from four aspects: key certificate storage, signature operation, verification operation, and total operation. To the best of our knowledge, this is the first PCS construction that supports privacy-preserving policy, so we compare PCS [1] and universal policy-controlled signature UPCS [2] with our proposed PCS-PP scheme. The result is shown in Table 2, where E be the computational cost of exponentiation in G P or G T , M is the computational cost of multiplication in G P , P is the computational cost of a bilinear pairing function, N is all of the attributes in the access policy, and I is the attribute that satisfies the policy.…”

The policy-controlled signature (PCS) scheme uses the access policy to control signature verification permission. However public access policy that may contain private information will leak user privacy. At the same time, the expressiveness of access structures in the PCS schemes is weak. Therefore, we propose a policy-controlled signature scheme with strong expressiveness and privacy-preserving policy (PCS-PP), in which linear secret sharing schemes is to design access structure which has strong expression, the three primes composite order bilinear groups is used to hide the attribute value into the attribute name that may expose the privacy data by data distortion concept. The proposed PCS-PP scheme not only has correctness and privacy-preserving policy, but also supports fine-grained signature verification. In addition, the unforgeability is proved in the random oracle model. Compared to the related schemes, the proposed PCS-PP scheme has superiority in features, computation cost and storage.INDEX TERMS Policy-controlled signature, privacy-preserving, linear secret sharing scheme, composite order bilinear groups.

“…Only a verifier who gratify the policies attached can verify the authenticity of the message. The belief of policy-controlled signatures resembles a few similarities with nominated verifier signatures, as it can also be used to assign a signature to numerous recipients [7]. Recently, there a new digital signature scheme with shared verification.…”

Information security is becoming more and more vital with the progress in the exchange of data. Protected communication in the network is a key necessity. Propose a novel technique to encrypt the image and embed the digital signature into the image. A digital signature is a procedure used to certify the authenticity and integrity of a message, software and digital documents. It is a also worn to give testimony of non-repudiation of communications. Steganography is an encryption technique that can be used along with cryptography as more-protected method rising to protect data. Images are the most admired cover objects used for steganography. In the province of digital images lots of different image file formats are present. Java technology proposed to authenticate the performance of the proposed model in circumstances of message length, key length, cipher text length and computational time for encryption and decryption.
