摘要: Systems and methods are disclosed for embedding information in software and/or other electronic content such that the information is difficult for an unauthorized party to detect, remove, insert, forge, and/or corrupt. The embedded information can be used to protect electronic content by identifying the content's source, thus enabling unauthorized copies or derivatives to be reliably traced, and thus facilitating effective legal recourse by the content owner. Systems and methods are also disclosed for protecting, detecting, removing, and decoding information embedded in electronic content, and for using the embedded information to protect software or other media from unauthorized analysis, attack, and/or modification.

摘要: Systems and methods are disclosed for protecting a computer program from unauthorized analysis and modification. Obfuscation transformations can be applied to the computer program's local structure, control graph, and/or data structure to render the program more difficult to understand and/or modify. Tamper-resistance mechanisms can be incorporated into the computer program to detect attempts to tamper with the program's operation. Once an attempt to tamper with the computer program is detected, the computer program reports it to an external agent, ceases normal operation, and/or reverses any modifications made by the attempted tampering. The computer program can also be watermarked to facilitate identification of its owner. The obfuscation, tamper-resistance, and watermarking transformations can be applied to the computer program's source code, object code, or executable image.

摘要: A shiftable memory supporting in-memory data structures employs built-in data shifting capability. The shiftable memory includes a memory having built-in shifting capability to shift a contiguous subset of data from a first location to a second location within the memory. The shiftable memory further includes a data structure defined on the memory to contain data comprising the contiguous subset. The built-in shifting capability of the memory to facilitate one or more of movement of the data, insertion of the data and deletion of the data within the data structure.

摘要: A method for cost entity matching can include constructing a first graph including a number of first entities and a number of second entities, and assigning a number of first cost values to each of a number of first edges connecting one of the number of first entities to one of the number of second entities in the first graph; adding a second graph to the first graph, wherein the second graph includes the number of first entities and the number of second entities, and assigning a second cost value to each of a number of second edges connecting one of the number of first entities in the first graph to the corresponding first entity in the second graph; and, matching each one of the number of second entities to one of the number of first entities based on the number of first cost values and the second cost values.

摘要: An algorithm or technique for compacting (and expanding) digital data is disclosed in which the data is broken up into words or lexemes. The words are entered into a push-down list as they are received and, if already on the list, a list location identifier is transmitted and the word moved to the top of the list. The last word on the list falls off the list when a new word is entered at the top and thereafter is treated as a new word. The data expander maintains identical lists and substitutes the data word for the list location code when received. Both hardware and software implementations are disclosed.
摘要翻译: 公开了一种用于压缩(和扩展)数字数据的算法或技术,其中数据被分解成单词或词汇。 这些字在接收到时被输入到下拉列表中,并且如果已经在列表中,则发送列表位置标识符并将该字移动到列表的顶部。 当在顶部输入新单词时,列表中的最后一个单词将被删除,此后被视为新单词。 数据扩展器维护相同的列表,并在收到列表位置代码时替换数据字。 公开了硬件和软件实现。
