摘要： •Introduce a joint privacy-preserving fingerprinting, decryption, and authentication.•Prevent encrypted data from being tampered without additional hash code/digest.•Achieve the lightweight encryption/decryption, and low transmission cost. Joint fingerprinting and decryption (JFD) is useful in securing media transmission and distribution in a multicasting environment. Common drawbacks of the existing JFD methods are the transmitted data may leak the content of data, and a subscriber cannot determine if a received image is modified such that tampering attack can be mounted successfully. Here we focus on security and privacy of image multicasting and introduce a new framework called JFDA (joint privacy-preserving fingerprinting, decryption, and authentication). It has several main characteristics, JFDA: (1) accomplishes fingerprinting in the encryption domain to preserve privacy and prevent encrypted data from being tampered without additional hash code/digest, (2) prevents tampering attack on the decrypted data to ensure the fidelity of the fingerprinted data, (3) makes user subscribing to a visual media be an examiner to authenticate the same visual media over the Internet. The effectiveness of the proposed method is confirmed by experimental results. 出版者： Elsevier Inc 出版日期： 2016-07-01 出處： Journal of Visual Communication and Image Representation, 2016-07, Vol.38, p.858-871 資源來源： ScienceDirect (Elsevier) Journals 版權： 2016 Elsevier Inc. 識別號： ISSN: 1047-3203 識別號： EISSN: 1095-9076 識別號： DOI: 10.1016/j.jvcir.2016.02.003
