    摘要: A method, computer program product and system for preventing unauthorized access of confidential information. The transmission of data from a first user to a second user is detected. An authorization level corresponding to the second user is then determined. Furthermore, a probability that the authorization level corresponding to the second user and the data is accurate is generated. Additionally, a determination is made that the data includes sensitive information that the second user is not authorized to access based on the authorization level. Moreover, the data can be modified based on the probability, where the data is to be redacted if the probability is within a range of a threshold value or the data is to be blocked from transmission if the probability is above the range.

    摘要: An example computer-implemented method includes receiving, via a processor, a plurality of structured query statements associated with an application and a database. The method includes detecting, via the processor, a logical relationship between at least two of the plurality of structured query statements based on a common source, a predetermined threshold time, a common transaction. The method includes generating, via the processor, a model based on the detected logical relationship. The method further includes receiving, via the processor, a request to modify the database. The method also further includes modifying, via the processor, the database in response to detecting that a predetermined threshold probability of application functionality impairment is not exceeded.

    摘要: Disclosed embodiments provide techniques for accessing a document from a cloud storage system and controlling the display of sensitive data within the document based on user permissions. One or more restricted information segments are identified within a document to be stored on the cloud storage system. Restricted information segments can include anything within an electronic file for which it is desired to provide multiple levels of access. In some embodiments, the restricted information segments are automatically identified via computer-implemented natural language processing (NLP) techniques. For each restricted information segment, one or more alternative data sequences are generated. The alternative data sequences are encrypted using various keys residing on a client device associated with a user. The keys can be used to decrypt data stored within a multiple-value encrypted field structure. In this way, multiple levels of information can be disseminated to an audience with various permission/privilege levels.

    摘要: Embodiments of the present invention disclose a method, computer program product, and system for text author anonymization for de-identification of written text. This may be used to replace written text after learning text author writing characteristics, such frequently written terms, grammar patterns, grammar errors, and writing tone. Portions of the written text which may identify the text author may be replaced, for example the text author writing characteristics, social status, geographical location, and specific organization.
