Abstract: Approaches for synchronizing data files across multiple systems are described. A user-specified value of a threshold indicative of a quantity of data is input to a computer processor and stored in processor-readable memory on one of the systems. A set of files of the replicated files that are unsynchronized between the one system and another system of the systems is determined, along with a quantity of data to be synchronized for the set of files. The files in the set of files are synchronized between the one system and the other system in response to the quantity of data to be synchronized satisfying the value of the threshold. Fewer than all of the set of files are synchronized in response to the quantity of data to be synchronized not satisfying the threshold.

Abstract: 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.

Abstract: Approaches for protecting a data element are disclosed. The method includes encrypting the data element with a first key on a first client system. A set of permissions is stored in association with the encrypted data element, and a first signature is generated from the set of permissions for the data element. The first key is encrypted with a second key on the first client system. The encrypted first key is stored in association with the encrypted data element, and the second key is encrypted with a public key of a public-private key pair of a first user on the first client system. The first signature and the encrypted second key are transmitted from the first client system to a server system for storage.

Abstract: A method of evaluating a particular document relating to property includes selecting the particular document from a set of pre-selected documents. Each pre-selected document has associated therewith one or more search linkages that identify how the pre-selected document was selected, using user-supplied inputs, from a larger set of documents relating to property. The method also includes using the one or more search linkages associated with the particular document to determine a relevance factor associated with the document. The method further includes displaying to a user information relating to the document.

Abstract: Methods and systems are disclosed for retrieving records. In one embodiment, the method comprises obtaining a starting record from a data set, obtaining a value associated with a first attribute of the starting record and executing at least one search for additional records in the data set associated with the value. The additional records are added to a result set. One of the records in the result set is selected and a value associated with a second attribute of the record is obtained. A second search for second additional records in the data set associated with the second value is executed. The second additional records are added to the result set. The records in the result set are outputted.
