    Abstract: An effective image tamper localization and self-recovery scheme that uses
    the rehashing model is proposed in this paper. The aim of the proposed scheme was to
    reduce the failure rate in detecting image tamper areas and achieve high rates of successful
    detection. To achieve this aim, the proposed scheme uses a set of hash functions which
    are called the rehashing model, gained an optimal decreasing collision method to detect
    tamper areas With an improved and accurate tamper detection rate, the tampered image
    can be recovered more accurately. The quality of the proposed scheme was tested with gray
    and color images. The experimental results indicated that the proposed scheme has good
    performance in locating tamper locations and allows image recovery with an acceptable
    visual quality up to 50% of the image content tampered.
