A novel data embedding method using adaptive pixel

  1. 1. A novel data embeddingmethod using adaptive pixelpair matching…….Presented by:RENUKA VERMA.(REG NO:3470910288)RESHMA BADAL.(REG NO:3470910290)DEPT:ECE-CBATCH NO: ECEC(10)Guided by:MR. P.SUBRAMANIAN(ASSOCIATE PROFESSOR)ECE DEPT
  2. 2. ABSTRACTThis paper proposes a new data-hidingmethod based on pixel pair matching (PPM).The basic idea of PPM is to use the values ofpixel pair as a reference coordinate, andsearch a coordinate in the neighborhood set ofthis pixel pair according to a given messagedigit.
  3. 3. The pixel pair is then replaced by the searchedcoordinate to conceal the digit. Exploiting modification direction (EMD) anddiamond encoding (DE) are two data-hidingmethods proposed recently based on PPM. The maximum capacity of EMD is 1.161 bppand DE extends the payload of EMD byembedding digits in a larger notational system.
  4. 4. The proposed method offers lower distortion than DE byproviding more compact neighborhood sets and allowingembedded digits in any notational system. Compared with the optimal pixel adjustment process(OPAP) method, the proposed method always has lowerdistortion for various payloads.Experimental results reveal that the proposed method notonly provides better performance than those of OPAP andDE, but also is secure under the detection of some well-known steganalysis techniques.
  5. 5. OBJECTIVE This project is a data hiding method based on PPM.. Exploiting modification direction (EMD) and diamond encoding (DE) are two data- hiding methods proposed based on PPM.

  7. 7. EXISTING SYSTEM: Least significant bit substitution method. This method is easy to implement with low CPU cost.
  8. 8. DISADVANTAGES OF EXISTING SYSTEM: Imbalanced embedding distortion emerges and is vulnerable to steganalysis. The existing technique can be easily cracked.
  9. 9. PROPOSED SYSTEM: Exploiting modification direction (EMD) and diamond encoding (DE) are two data-hiding methods proposed recently based on PPM.
  10. 10. ADVANTAGES OF PROPOSED SYSTEM: better performance than those of OPAP and DE. secure under the detection of some well- known steganalysis techniques.
