Improved duplicate and near-duplicate detection techniques may assign a number of fingerprints to a given document by (i) extracting parts from the document, (ii) assigning the extracted parts to one or more of a predetermined number of lists, and (iii) generating a fingerprint from each of the populated lists. Two documents may be considered to be near-duplicates if any one of their fingerprints match.

A duplicate apparatus is disclosed that is able to reliably switch plural document feeding units without additional cost and has high accessibility. In the duplicate apparatus, an operations unit and a document reading unit are included in an operations-reading unit as one unit, and plural operations-reading units can be connected to the duplicate apparatus. A control unit enables one of the operations-reading units to operate via an image data selection unit and an operations selection unit.

Data present on identification cards in a high-embossed form are protected against attempted forgery and falsification. This protection consists in providing on the identification card, along with the data record in a high-embossed form, a second identical data record which may be visually tested without auxiliary means and is inscribed in the identification card by means of a laser recorder.

In a selective call receiver for presenting a plurality of messages to a user, a method comprises the steps of receiving (205) a message, storing (208) the received message in a memory, and determining (210) whether the received message is substantially equivalent to previously stored messages. A further step includes displaying (225) a duplicate message icon if the received message is a duplicate message that is substantially equivalent to one of the previously stored messages.

Packager for rolled sections with a duplicate cycle comprising a conveyor (2) of rolled sections, means (4-6) designed to form the layers (3', 3") of rolled sections each having a predetermined number of rolled sections, means (10) designed to pick up a layer (3) of sections from said conveyor (2) and transfer said layer (3) to means (26, 35) of forming packages of sections working with package-removal means (36), said means (10) designed to pick up a layer (3) of sections comprising means (16) ...

A network communication system with duplicate device detection in which a mobile communication unit, attempting to register to a communication network with a duplicate identification code as that of another mobile communication unit already registered, is detected and refused registration to the network. As a result, the mobile communication unit already registered to the network is not deregistered. Furthermore, the network communication system is not locked-up due to the existence within the s...

A computer system for duplicate bridge scoring utilizes a compact data card to remain attached to a duplicate board during the session of play. The card is arranged for encoding of data round-by-round rather than by player line. The computer unscrambles the pair numbers by formula or reference, the variable number of tables for each of the sections being communicated to the computer after the session starts. The data card is made sufficiently compact by the aid of the round-by-round array; by un...

The invention concerns a detection of duplicate tuples in a database. Previous domain independent detection of duplicated tuples relied on standard similarity functions (e.g., edit distance, cosine metric) between multi-attribute tuples. However, such prior art approaches result in large numbers of false positives if they are used to identify domain-specific abbreviations and conventions. In accordance with the invention a process for duplicate detection is implemented based on interpreting reco...

A method for detecting duplicate records generates a checksum (222) for each record and compares the generated checksum (222) to checksums stored in check files (30). In a particular application, a system (10) for processing call detail records utilizes a duplicate check module (28) that detects duplicate records using checksum processing.
