  • Publication number: 20210334873
    Abstract: An indexing value may be determined, transparently with respect to a data user, based on a desired plaintext item of data and a transformation expression. The indexing value may be used to access an entry in an indexing structure to obtain a corresponding CryptoJSON record which includes a non-deterministically encrypted ciphertext item. Different versions of an export policy may change the ways in which the search is performed based on calculation of a numerical representation of an ECCN for the vendor access. In another embodiment, an indexing structure for a CryptoJSON recordset may be accessed. Positions of items of the indexing structure may be based on corresponding plaintext items. References related to the corresponding plaintext items in the indexing structure may be encrypted and other information in the indexing structure may be unencrypted.

  • Publication number: 20170134159
    Abstract: The present invention is directed to methods and systems in which TNO ciphertexts are grouped into targeted selections for distributed aggregation. A user selects certain initial data records for Stage-1 processing, which performs mapping operations and partitioning with the data records. An owner key is obtained from the data owner for encrypting and decrypting of the TNO ciphertexts. Consents are obtained from the data subjects for encrypting and decrypting of partition keys and indexes. Stage-2 processing are distributed among multiple processing units based on the indexes, where associated TNO ciphertexts are decrypted and processed to obtain aggregate data.

  • Publication number: 20160350544
    Abstract: A method for sharing encrypted data and encryption keys through a system comprised of the following data types, but not limited to a; 1) Record and its encryption key, 2) RecordSet and its encryption key, and 3) Entity and its encryption key. A Record is encrypted using an encryption key, furthermore, the Record encryption key is encrypted using a RecordSet encryption key, and finally, both the encrypted Record and its encrypted encryption key are wrapped as a single unit, to avoid key the expensive operations of key lookup and general key operation overhead. Access control to the RecordSet encryption keys are provided by a combination of data types, but not limited to a; 1) Entity and its encryption key, 2) Ciphers, and 3) Trusted Entity Lists. For each Entity which is authorized access to access a RecordSet, an encrypted Cipher, made of both the Entity encryption key and RecordSet encryption key, is added to a Trusted Entity List.

  • Publication number: 20160234180
    Abstract: The present invention is directed to methods and systems in which data are stored as encrypted records on a computer usable medium, and search requests are processed based on user identities to retrieve the data without decrypting all the stored records. Individual decryption keys are associated with identities of respective owners, without being revealed to the owners and are kept internal inside a computer. Finally, all keys are overwritten from the computer usable medium upon completion of each search request to take access away from a superuser or any unauthorized access to the system.

  • Patent number: 9380034
    Abstract: Systems and methods are provided in which external key devices are used for sealing and unsealing data-gathering devices without Internet, wherein the data-gathering devices invalidate the external key devices upon completing data collection in order to seal removable storage. Further, a sealed removable storage is transported to same location of a key server, where the key server uses a multi-factor sealing routine to unlock the sealed removable storage. The routine seals and unseals uses multiple factors including a location of the key server, hardware attributes of the removable storage, hardware attributes of the external key devices, and a private key of the key server. The data-gathering device may be used to support workers collecting data in disconnected parts in the world that are without Internet. The workers may collect data by using mobile devices to transfer data to a shared data-gathering device.

  • Publication number: 20110264638
    Abstract: Various systems and methods for communicating enterprise information between an enterprise backend server and a mobile device are provided. For example, a middleware server may generate a formbuilder interface that allows a user to input form design information used to display a custom dynamic form. The form design information may include a plurality of form elements and an executable script that in part controls a behavior of the custom dynamic form. The custom dynamic form may be configured to prompt input of and receive the enterprise information. A value of a first one of the plurality of form elements may cause an action to be taken by the custom dynamic form, wherein the executable instruction when executed causes the action to be taken. The middleware server may communicate to the mobile device the plurality of form elements and the executable instruction. An operator of the mobile device may provide enterprise information using the custom dynamic form.

  • Patent number: 6377075
    Abstract: There is disclosed a circuit topology for avoiding transistor gate oxide- dielectric breakdown and hot-carrier degradation in circuits, such as CMOS inverters, fabricated in a standard sub-micron CMOS process with feature size below 0.8 &mgr;m and gate-oxide thickness less than 150 Å. An inverter circuit according to the invention incorporates transistors M6, M2, M3, M5 appropriately biased, additional to those of a standard inverter circuit (comprising M1 and M4), in order to avoid hot-carrier degradation and gate-oxide breakdown of M4 and M1. The invention is also applicable to transistor circuits having other functionalities for example logic level translators.
