Fragile Watermarks
US Patent:
7730037, Jun 1, 2010
Filed:
Oct 17, 2005
Appl. No.:
11/250460
Inventors:

International Classification:
G06F 7/00
G06F 17/30
G06F 17/30
US Classification:
707687, 713176
Abstract:
Disclosed is a fragile watermarking scheme for detecting and localizing malicious alterations made to a database relation with categorical attributes without introducing distortions to cover data. A watermark for a tuple group may be inserted by selectively switching the position of tuples in tuple pairs using a tuple hash associated with each tuple in the tuple pair; and a corresponding bit in a watermark derived from the tuple group using a embedding key, a primary key and hash functions.
Method And Apparatus For Watermarking Stream Data
US Patent:
2006027, Dec 7, 2006
Filed:
May 23, 2006
Appl. No.:
11/419800
Inventors:
Sushil Jajodia - Oakton VA, US
Huiping Guo - Monterey Park CA, US
YingJiu Li - Singapore, SG

International Classification:
H04L 9/00
US Classification:
713176000, 380255000
Abstract:
A watermarking system embeds a watermark into data values that may be streamed. A data hash is calculated using data values and a hash key. The data values are grouped. The groups include a first group and a second group. A first group hash is calculated using data values in the first group and a first group hash key. A second group hash is calculated using data values in the second group and a second group hash key. A watermark is constructed based on the first group hash and the second group hash. The value of at least one of the data values in the first group is modified using the watermark.
