cryptographic hash functions or the hardness of the Discrete-Logarithm problem. ...
A negative database is a privacy-preserving storage system that allows to efficiently test if an entry is present, but makes it hard to enumerate all encoded entries. ...
Negative Databases from Cryptographic Hash Functions Cryptographic hash functions such as SHA-256 [14, 16] and RIPEMD-160 [7, 14] are widely used cryptographic primitives. ...

As of today, in a pre-step process hash values of files are generated and stored in a database; typically a cryptographic hash function like MD5 or SHA-1 is used. ...
Later the investigator computes hash values of files, which he finds on a storage medium, and performs look ups in his database. ...
Anti-Blacklisting Anti-blacklisting means that we are able to efficiently generate false negatives from Kornblum's point of view. To explain this let a known-to-be-bad file F 1 be given. ...

The advantage of a cryptographic hash function is in turn that its values do not allow any conclusions about the structure of an image. ...
Cryptographic hash functions, on the other hand, create a unique bit-sensitive value. With these, no similarity measurement is possible, since only with exact agreement a picture is found. ...
Cryptographic Hash We need a cryptographic hash function that hashes the preceding robust hashes. ...

Besides identifying exact duplicates, which is mostly solved using cryptographic hash functions, it is also helpful to detect similar data by applying approximate matching. ...
In contrast, cryptographic hash values are stored within binary trees or hash tables and hence the lookup complexity of a single digest is O(log 2 (x)) or O(1), respectively. ...
Efficiency in general Let S D denote the hashes of files from a device and let S B denote database set (i.e., the blacklist). ...
