“…In [65] a scheme is designed where images embedded in the spatial domain resist JPEG compression. The work by [66] proposes a semi-fragile scheme based on IWT transform and histogram shifting technique, the cover image is divided into nonoverlapping blocks, IWT coefficients are obtained for each block and then a multi-level histogram shifting mechanism is applied to insert the watermark bits. When no attacks occur the schee is completely reversible and it is semi-fragile against JPEG compression.…”

In recent years, the growth of the Internet along with multimedia data delivery, have caused the misuse and even alteration of the original digital content. As a security mechanism, digital watermarking has been used to protect digital content, traditionally in copyright protection applications, and more recently digital watermarking has been used in content enhancement applications. Regardless of the application, digital watermarking schemes always cause some level of signal degradation. There are however, certain applications as in the military or medical fields, where loss of information cannot be tolerated during the reconstruction of host signals, therefore conventional watermarking schemes do not satisfy the quality requirements. In order to reconstruct signals without loss of data, reversible watermarking is employed. Recent research in reversible watermarking has focused on either, the improvement of embedding capacity or the reduction of perceptual impact of the schemes, but scarcely exploring the robustness of reversible schemes. In this survey, we provide a deep review of reversible watermarking schemes and propose a new classification outline based on the robustness point of view. Finally, some future directions for reversible watermarking research are presented and open problems in robust reversible watermarking are outlined. INDEX TERMS Digital watermarking, multimedia content, reversible watermarking, robustness.

2) ABSTRAK Pengiriman data melalui media elektronik semakin pesat. Banyak data yang gunakan transkasi internet adalah data rahasia. Salah satu data rahasia ialah data medis seorang pasien. Pada umumnya data medis pasien tidak hanya terdiri dari satu buah citra saja, melainkan data citra yang jumlahnya lebih dari satu. Sehingga diperlukan suatu mekanisme penyemebunyian (steganografi) data medis pasien yang jumlahnya lebih dari satu kedalam sebuah media pembawa, agar data ini dapat terlindungi dari pihak-pihak yang tidak berkepingan. Pada penelitian ini menerapkan discrete cosine transform dalam steganografi citra. Cover dan pesan rahasia steganografi yang digunakan berupa citra dengan ukuran 512px X 512px. Pada proses penyisipan data rahasia yang jumlahnya banyak diterapkan denagn multi-level menggunakan sekma multi-scale image sharing (MSIS). Dalam proses pengujian digunakan citra cover 24 bit. Pada citra cover 24 bit yang digunakan memiliki format .png. Proses parameter analisis pengujian menggunakan Peak Signal to Noise Ratio, Mean Squared Error, Normalized Cross Correlation, Average Difference, Structural Content, Maximum Difference, Normalized Absolute Error serta dari sisi size. Hasil Peak Signal to Noise Ratio pada penyisipan level 1 dan level 9 bernilai kurang lebih 40 db dan 24 db.
