A billing process is disclosed for a information dispersal system or digital data storage system. In one embodiment of the invention, the original data to be stored is separated into a number of data “slices” or shares in such a manner that the data in each subset is less usable or less recognizable or completely unusable or completely unrecognizable by itself except when combined with some or all of the other data subsets. These data subsets are stored on separate digital data storage devices as a way of increasing privacy and security. As dispersed file shares are being stored or removed from a grid of distributed storage locations, a set of metadata tables are created, separate from the dispersed file share storage, to maintain information about the original data size of each block, file or set of file shares dispersed on the grid. The original data size information in these separate metadata tables is used to determine usage information based upon the original file size even though the file has been dispersed onto a storage grid that contains file slices who size may not relate to the original file size and the file slices may have been compressed by the system in order to reduce storage space or improve transmission time. As such, the billing process is able to enable a broad range of commercial billing options for billing for commercial data services on an information dispersal grid.

A malware detection system seeking to identify computer viruses, worms, Trojans, banned files and the like acts to determine from the file name, file size and storage location of a computer file being tested, whether that computer file potentially matches a specific known malware free computer file stored within a list of such specific known malware free computer files. If a match occurs indicating that the candidate computer file is potentially the specific known malware free computer file, then this is confirmed by calculating a checksum of the candidate computer file and comparing this against a stored corresponding checksum of the specific known malware free computer file. If these checksums match, then the candidate computer file can be passed as clean without requiring further time consuming malware detection scanning.

DNA is a natural molecular level storage device. Molecular storage devices use each molecule or part of it for storing a character. Thus it is possible to store information million of times than presently used storage devices. For example a JPEG image (i.e. flag of India) having file size of 1981 Bytes can be encrypted using 7924 DNA bases which occupies about 2694.16 nanometers In other words flag of India can be encrypted 8.07×105 times in human genome which comprises 6.4×109 DNA bases and occupy a tiny volume of about 0.02 μm3. A method for storing information in DNA has been developed which includes software and a set of schemes to encrypt, store and decrypt information in terms of DNA bases. The main advantages of the present method over exiting art is that it addresses complete set of extended ASCII characters set and thereby, encryption of all kind of digital information (text, image, audio etc.). First of all, information is, encrypted along with carefully designed sequences known as header and tail primers at both the ends of actual encrypted information. This encrypted sequence is then synthesized and mixed up with the enormous complex denatured DNA strands of genomic DNA of human or other organism.

A circuit layout methology is provided for eliminating the extra processing time and file-space requirements associated with the optical proximity correction (OPC) of a VLSI design.

The attachment configuration module can be incorporated into a system for configuring packages of application files, designated from within user applications, to be sent as e-mail attachments in e-mail communications.

A baseline for internet traffic duration is established by (i) collecting internet traffic data regarding file size, server response time, packet loss and round trip time, (ii) removing from this data outliers associated with file size, server response time and packet loss per client type, and (iii) organizing any remaining data into round trip time bins according to median values of round trip time per client type. Thereafter, historical or newly collected Internet traffic data is compared against threshold values for each round trip time bin to locate duration outliers. These duration outliers are indicators of congestion and congestion episodes may be identified by the continued presence of such outliers over successive time intervals.

Search results of a search query on a network are ranked according to an additional ranking function for the prior probability of relevance of a document based on document property. The document property may be the document's file type, the file size, the document language, or another query-independent property of the document. The query-independent values for each document property may be weighted according to relevance measurements of the document based on the document property. As more relevance measurements of the documents may be obtained, the query-independent values for each document property may be updated to reflect the new measurements.

A differential compression method and computer program product combines hash value techniques and suffix array techniques. The invention finds the best matches for every offset of the version file, with respect to a certain granularity and above a certain length threshold. The invention has two variations depending on block size choice. If the block size is kept fixed, the compression performance of the invention is similar to that of the greedy algorithm, without the expensive space and time requirements. If the block size is varied linearly with the reference file size, the invention can run in linear-time and constant-space. It has been shown empirically that the invention performs better than certain known differential compression algorithms in terms of compression and speed.

The objective of the present invention is to manage reference movies using an index file, without causing the user to be perplexed. The reference movies are generated because of, for instance, the upper limit of the file size. The index file manages sets of information regarding the files being managed. Examples of these sets of information are information for determining whether or not a file is presented to the user, information for determining whether or not a file is original, and information indicating whether or not nondestructive editing has been done. Based on such information, the erasure, displaying a list, and so on are carried out. Thus, it is possible to manage the reference movies using the index file, without causing the user to be perplexed.

An encoder uses multi-pass VBR control strategies to provide constant or relatively constant quality for VBR output while guaranteeing (within tolerance) either compressed file size or, equivalently, overall average bitrate. The control strategies include various techniques and tools, which can be used in combination or independently. For example, in a first pass, an audio encoder encodes a sequence of audio data partitioned into variable-size chunks. In a second pass, the encoder encodes the sequence according to control parameters to produce output of relatively constant quality. The encoder sets checkpoints in the second pass to adjust the control parameters and / or subsequent checkpoints. The encoder selectively considers a peak bitrate constraint to limit peak bitrate. The encoder stores auxiliary information from the first pass for use in the second pass, which increases the speed of the second pass. Finally, the encoder compares signatures for the input data to check consistency between passes.

A computer-implemented method and a distributed file system in a distributed data network in which file metadata related to data files is distributed. A unique and non-reusable mode number is assigned to each data file that belongs to the data files and a directory of that data file. A key-value store built up in rows is created for the distributed file metadata. Each of the rows has a composite row key and a row value (key-value pair) where the composite row key for each data file includes the mode number and a name of the data file. When present in the directory, the data file is treated differently depending on size. For data files below the maximum file size the entire file or portion thereof is encoded in the corresponding row value of the key-value pair. Data files above maximum file size are stored in large-scale storage.

The present invention concerns an electronic forensic tool for conducting electronic discovery and computer forensic analysis. The present invention allows a non-technical person such as a non-forensic expert to conduct electronic discovery and thereby obviate the need for an expert in many situations. The present invention allows for electronic discovery in a forensically sound manner. The present invention also concerns a business method for electronic discovery involving a software program and a command server for generating expanded functionality. The client software may be distributed at minimal or no cost, preferably as a CD. Using the client software, a user boots a target machine to determine whether a target machine contains data of interest. The client software will, however, only display limited data such as file information, date, last modified, and file size. To access and examine the actual underlying data, the user must obtain additional functionality, e.g. by purchasing a command block from the control server. The additional functionality will allow the client program to extract the data of interest or the entire contents of the target machine to an external device for further analysis.
