In a coding system, input data within a system is encoded. The input data might include sequences of symbols that repeat in the input data or occur in other input data encoded in the system. The encoding includes determining a target segment size, determining a window size, identifying a fingerprint within a window of symbols at an offset in the input data, determining whether the offset is to be designated as a cut point and segmenting the input data as indicated by the set of cut points. For each segment so identified, the encoder determines whether the segment is to be a referenced segment or an unreferenced segment, replacing the segment data of each referenced segment with a reference label and storing a reference binding in a persistent segment store for each referenced segment, if needed. Hierarchically, the process can be repeated by grouping references into groups, replacing the grouped references with a group label, storing a binding between the grouped references and group label, if one is not already present, and repeating the process. The number of levels of hierarchy can be fixed in advanced or it can be determined from the content encoded.

A packet classification device includes a CAM device, an SRAM device, and a control circuit that controls and coordinates the operations of the CAM and SRAM devices. For some embodiments, a first CAM block stores unique entries for each packet header field, a RAM block coupled to the first CAM block stores field labels for the unique packet header fields, a second CAM block stores group labels consisting of unique combinations of concatenated field labels, and a second RAM block coupled to the second CAM block stores a group identification (ID) for each group label, wherein each group ID identifies a corresponding one of the groups of rules.

Publishers define relationships between their own content items (e.g., World Wide Web pages) and content items created or maintained by other publishers. A central namespace manager provides grouping labels that publishers insert into their content items. Content items having matching grouping labels are identified as related. Different classes of grouping labels can be used to define different types of relationships, and multiple classes of grouping labels can co-exist. Grouping labels are made available to an information server such as a search server, which uses the labels in identifying content items related to a currently displayed content item.

The present invention provides a technical scheme of real time communication among a plurality of members in a real time communication group. A real time communication group server is independent to a real time communication server. One or more group labels and a real time communication label of each member in the real time communication group labeled by every group label are preset in the real time group server. The real time communication group server uses each group label as the real time communication label to simulate that a real time communication client automatically log in the real time communication server, real time information from the real time communication client sent by the real time communication server is received, and the real time information is respectively transmitted to real time communication clients corresponding to other members in the real time communication group through the real time communication server. As the real time communication group server is independent to the real time communication server, the real time communication group server can support a plurality of real time communication platforms.

The invention discloses a group RFID tag identity authentication method, capable of meeting the actual application requirement of an RFID system. The method provided by the invention is low in requirement on hardware of a tag side, meets the requirement of an ultra lightweight protocol, can achieve the identity authentication process of a group RFID tag, and is applicable to solving the group RFID tag identity authentication problem of the RFID system with low cost.

A method for the automated analysis of digital images, particularly for the purpose of assessing the presence and severity of cancer in breast tissue based on the relative proportions of tubule formations and epithelial cells identified in digital images of histological slides. The method includes the step of generating a property co-occurrence matrix (PCM) from some or all of the pixels in the image, using the properties of local mean and local standard deviation of intensity in neighbourhoods of the selected pixels, and segmenting the image by labelling the selected pixels as belonging to specified classes based upon analysis of the PCM. In this way relatively dark and substantially textured regions representing epithelial cells in the image can be distinguished from lighter and more uniform background regions Other steps include identifying groups of pixels representing duct cells in the image based on intensity, shape and size criteria, dilating those pixels into surrounding groups labelled as epithelial cells by a dimension to correspond to an overall tubule formation, and calculating a metric based on the ratio of the number of duct pixels after such dilation to the total number of duct and epithelial pixels. Other uses for the method could include the analysis of mineral samples containing certain types of crystal formations.

The invention discloses an RFID group label authentication protocol based on a Hash function. The RFID group label authentication protocol comprises the following steps: step 1, a reader sends an inquiry request message to a label in a reading range of the reader; step 2, the reader sends the response messages of all the tags to a background database; step 3, the background database determines a group identifier and an invalid identifier of the label according to the label response message sent by the reader, and selects one group identifier; 4, the background database authenticates all the labels in the selected group; 5, the group label authenticates the background database; and step 6, the group identifier is updated by the group label and the background database. A one-way hash function is adopted to encrypt a message needing to be transmitted, and a random number is used to randomize the transmitted message, so that anonymity and non-traceability of the label are realized; and meanwhile, the new and old group identifiers are stored in the background database, so that the method can well resist the desynchronization attack. A timeout retransmission mechanism is adopted to ensure that the response messages of all the tags in the group are received, and the integrity of the tags in the group is ensured.

The invention discloses a method, a system and a server for logging in chat groups based on a mobile terminal. The method comprises the following steps that: the server acquires the user information of a login user and acquires the group information of each chat group, wherein the group information mainly comprises a chat group label; and the server performs group selection to obtain temporary assignment information which corresponds to the user. The group selection step comprises the following sub-steps of: detecting whether the login user reserves a certain chat group, wherein when the login user reserves the chat group, the temporary assignment information mainly comprises the reserved chat group; and when the login user does not reserve the chat group, retrieving the chat group labels, setting public chat groups which correspond to part of or all of the user information of the user as temporary chat groups of the user, and setting the temporary chat groups as the temporary assignment information of the user. The invention has the advantage that: the chat groups which are reserved by the user are taken into consideration, so the user can enter the interesting chat groups more quickly and more accurately.
