Techniques for sharing content among multiple users are described herein. According to one embodiment, content is received from an owner to be shared among multiple members of one or more communities, where the owner defines the one or more communities. In response to the received content, a privacy level associated with the content to be shared is determined, where the privacy level is assigned by the owner. A trust level associated with each member of the one or more communities is determined, where each member is associated with a trust level assigned by the owner previously to represent a relationship between each member and the owner. The content is shared among selected members of the one or more communities if trust levels of the selected members and the privacy level associated with the content satisfy a predetermined relationship. Other methods and apparatuses are also described.

The present invention provides methods and apparatus to protect user privacy while accessing information in public places, using both public and personal devices. This is achieved by employing a mechanism that prevents private information from being displayed on public devices. Instead, this type of information is made available only to a user's personal device(s) that the user carries and/or trusts. An example embodiment of the invention shows relevant parts of the information content, referred to also as information documents or simply documents, to multiple devices based on privacy level and user preferences. Embodiments of the present invention also provide personalized services based on privacy levels defined by users. These users can for example be customers of a retail store. The service provided is sometimes also based on user history of accessing information documents. It permits personalized information to be sent to a customer's personal device.

A method of providing an electronic business card (EBC) access and organization service on the Web. The cardholder database is accessible and searchable from any browser connected to the Internet or the EBC service may be installed behind a conventional firewall and thus accessible only to intranet users. The service thus provides easy access to cardholder contact information with privacy assured by use of integrated access restrictions. Access to and delivery of contact information by the service is not limited to a Web browser interface as commonly known today. The service provides multi-mode access and/or data delivery interfaces. The service also provides an export feature that formats search results into a pre-defined file structure readable by a conventional contact management programs. Custom export file formats may also be defined provide even wider connectivity and cross-platform utility. Access to individual records is controlled at both the record level and the field level, with multiple privacy levels for each field, in addition to the well-known “public” and “private” levels. Users having certain permissions are permitted to read a defined group of records, though not necessarily all fields in each record. A location tracking feature is also provided to allow the cardholder to rapidly designate a pre-defined contact location. Alternately, the cardholder may define a temporary contact location not normally stored in the database system. Electronic mail sent by the cardholder is automatically formatted to contain a signature hypertext link directing recipients of the email to the EBC service. This hyperlink enables the recipient of the email to rapidly access the EBC system to locate the cardholder and/or obtain additional information.

The subject invention provides a unique system and method that facilitates a controlled communication environment which allows a user to participate in a plurality of privacy contexts with other people in a simultaneous manner in an online community. A user can assign or define varying levels of privacy to his/her information or content to control the visibility of such information by others. In particular, a first user can maintain one or more “gardens” or stores of content which may be accessible to at least a subset of the online community. Access to the contents of any one garden can be based on the privacy level of the garden and the privacy level (e.g., access parameters) granted to the person. The privacy levels and arrangement of content can be hierarchal and/or non-overlapping. Thus, a user can seamlessly communicate with multiple users at the same time regardless of their context or privacy level while maintaining the privacy boundaries of each garden.

Methods, systems and related computer products for providing entitlement controlled levels of collaborative exchange of data using a computer network of Subscribers and Publishers, are configured to: (a) define a set of different privacy levels, each privacy level having associated data sharing parameters that control a participating Publisher's ability to send and a participating Subscriber's ability to receive content specific data; and (b) provide an electronic privacy level register that defines the different data sharing parameters for each of the different privacy levels and identifies an associated at least one privacy level for each participating Subscriber and Publisher.

A system for implementing search- and retrieval-compatible data obfuscation includes an annotator that annotates data, metadata, and relationships thereof that are privacy sensitive according to privacy policies. The system also includes an indexing server that indexes the annotated data according to the policies that specify rules for controlling access to the data. The system also includes an obfuscation server for serving user requests for data search and retrieval, and specifies data entitlement and access rights for the users by applying the privacy policies to user profiles. In response to receiving a search request from a user, the obfuscation server forwards the search terms in the request, along with a privacy level determined from a corresponding user profile and the policies, to a search engine that searches indices of a database having the privacy level in the request, and returning to the user only the results which match the search terms and the privacy level. In response to receiving a data retrieval request, the obfuscation server retrieves the requested data with annotations from the database, applies the obfuscation scheme to the annotated data according to the privacy policies and the user profile, and returns to the user the obfuscated data in compliance with the privacy policies.

A method and apparatus for ensuring a level of privacy for answering a convolution query on data stored in a database is provided. The method and apparatus includes the activities of determining (402) the level of privacy associated with at least a portion of the data stored in the database and receiving (404) query data, from a querier, for use in performing a convolution over the data stored in the database. The database is searched (406) for data related to the received query data and the data that corresponds to the received query data is retrieved (408) from the database. An amount of noise based on the determined privacy level is generated (410) and added (412) to the retrieved data to create noisy data which is then communicated (414) to the querier.

The invention provides a location anonymization-based privacy protection method. The method comprises the steps of 1) determining an anonymity degree k according to a currently queried privacy level, wherein the higher the privacy level is and the higher the anonymity degree k is; 2) creating a plurality of candidate anonymity sets with k elements by taking the anonymity degree k as the size of a currently queried anonymity set; 3) searching for one candidate anonymity set with a maximum query probability set entropy from the created candidate anonymity sets to serve as the anonymity set; 4) generating an upper bound and a lower bound of an anonymity distance according to the privacy level, wherein the higher the privacy level is, the larger the upper bound of the anonymity distance is, and the larger the lower bound of the anonymity distance is; and 5) generating an anonymous location used for replacing a currently queried real location according to the generated upper bound and lower bound of the anonymity distance in the range of the anonymity set. The invention furthermore provides a corresponding privacy protection apparatus. According to the method and the apparatus, the LBS (Location Based Service) quality is improved while the location privacy protection is realized, and different demands of different users on privacy protection can be guaranteed.

The invention relates to a blockchain-based personalized k-anonymity privacy protection motivation method. When the privacy levels of clients are same, buyer clients and seller clients conduct an auction game according to the screening conditions in a smart contract, the winning buyer clients and seller clients are selected out to form an anonymity group, and the clients in the anonymous groups upload the positions of the clients and query requests to a server side together to achieve the k-anonymity process. When the privacy levels of the clients are different, the buyer clients are divided into multiple groups according to the sequence that the privacy levels needed by the buyer clients are increased, an anonymity group is formed by the buyer clients screened out from the buyer client groups of which the numbers n of the buyer clients are larger than k+1, and a k-anonymity group is formed by the seller clients and buyer clients in the other groups. According to the method, the privacy level requirements of different users can be met to complete different privacy levels of k-anonymity privacy protection, and by applying the decentralized smart contract, the security hazards of a trusted third party are avoided.
