Approaches for searching for key terms in a plurality of files include associating a respective key map with each file of the plurality of files in memory of a server. Each key map includes a plurality of bit values and each bit value indicates for a key term whether or not the key term is present in the associated file. The server inputs a search map, and the search map includes a plurality of bit values. Each bit value in the search map indicates for a key term whether or not the key term is a key term to search. The server determines for each key map, whether or not the key map satisfies the search map. Data indicating each file of the plurality of files having an associated key map that satisfies the search map is output by the server.

Searching data files using a key map

In an approach for protecting against use of clones of electronic devices, a first sequence value is initialized on the server and an equal second sequence value is initialized on an electronic device. In response to a first login request to the server from a user operating the electronic device, the first and second sequence values are compared. If the values are equal, processing of the login process continues. Otherwise, the login request is rejected. If the login is successful, a next value is computed for the first and second sequence values, and the next first and second sequence values are stored on the server and on the electronic device, respectively.

Protection against unauthorized cloning of electronic devices

Approaches for deduplicating data include generating a first key from plain text data of a first data element. The first data element is encrypted using the first key. The first key is compared to each key of a plurality of previously stored keys, which are associated with other encrypted data elements. In response to the first key matching a second key of the plurality of previously stored keys, the encrypted first data element is compared to the other encrypted data element associated with the second key. In response to the encrypted first data element matching the other encrypted data element, the first key is associated with the other encrypted data element, and the encrypted first data element is discarded.

Data deduplication with encryption

Methods and systems are disclosed for generating a public-private key pair. A programmed processor displays a plurality of questions and inputs two or more answers to two or more of the plurality of questions in response to user input. The processor computes the public-private key pair as a function of the two or more answers to the two or more questions and stores the public-private key pair in memory coupled to the processor.
