The security problem of screen image leakage on a cathode-ray tube (CRT) through electromagnetic radiation from several meters away, “transient electro-magnetic pulse emission surveillance technology” (TEMPEST), has attracted wide interest by security researchers since Van Eck wrote about this problem. On the industry side, the problem is considered a serious risk, especially for computers used in...
In this paper we present a method for hiding a list of data by mixing it with a large amount of superfluous items. The technique uses a device known as a negative database which stores the complement of a set rather that the set itself to include an arbitrary number of garbage entries efficiently. The resulting structure effectively hides the data, without encrypting it, and obfuscates the number...
To reconcile the demand of information dissemination and preservation of privacy, a popular approach generalizes the attribute values in the dataset, for example by dropping the last digit of the postal code, so that the published dataset meets certain privacy requirements, like the notions of k-anonymity and ℓ-diversity. On the other hand, the published dataset should remain useful and not over generalized...
