20100246827 | USER-SPECIFIED SHARING OF DATA VIA POLICY AND/OR INFERENCE FROM A HIERARCHICAL CRYPTOGRAPHIC STORE - The claimed subject matter relates to architectures that can construct a hierarchical set of decryption keys for facilitating user-controlled encrypted data storage with diverse accessibility and hosting of that encrypted data. In particular, a root key can be employed to derive a hierarchical set of decryption keys and a corresponding hierarchical set of encryption keys. Each key derived can conform to a hierarchy associated with encrypted data of the user, and the decryption capabilities of the decryption keys can be configured based upon a location or assignment of the decryption key within the hierarchy. The cryptographic methods can be joined with a policy language that specifies sets of keys for capturing preferences about patterns of sharing. These policies about sharing can themselves require keys for access and the policies can provide additional keys for other aspects of policy and or base-level accesses. | 09-30-2010 |
20120029938 | Anonymous Healthcare and Records System - Described herein is using cryptographic techniques (anonymous proof systems) to ensure the anonymity of health records when processing payment claims related to insurers and pharmacies. A patient receives a patient token from an insurer, which the patient delegates to a healthcare provider. The delegated token is processed into an anonymized token that identifies the healthcare provider and the medical service provided, without including information by which the patient is directly identifiable. The anonymized token includes data by which the insurer validates the token. For prescriptions, an anonymized token may be generated as an endorsement for the patient (e.g., a printed barcode) and an unendorsed token transmitted to the pharmacy. The pharmacy combines data of the endorsement and the unendorsed token into an anonymous combined token that is transmitted to the insurer for payment. | 02-02-2012 |
20120331283 | USER-CONTROLLED DATA ENCRYPTION WITH OBFUSCATED POLICY - An obfuscated policy data encryption system and method for re-encrypting data to maintain the confidentiality and integrity of data about a user when the data is stored in a public cloud computing environment. The system and method allow a user to specify in a data-sharing policy who can obtain the data and how much of the data is available to them. This policy is obfuscated such that it is unintelligible to the cloud operator and others processing and storing the data. In some embodiments, a patient species with whom his health care data should be shared with and the encrypted health care data is stored in the cloud in an electronic medical records system. The obfuscated policy allows the electronic medial records system to dispense the health care data of the patient to those requesting the data without disclosing the details of the policy itself. | 12-27-2012 |
20130097417 | SECURE PRIVATE COMPUTATION SERVICES - An encryption scheme allows meaningful, efficient computation of encrypted data in various application domains, including without limitation patient health care, financial analysis, market research, and targeted advertising. Data providers, computational services, and results consumers work in concert using a somewhat homomorphic encryption scheme to preserve the secrecy while providing practical computational performance. Encrypted data is stored within network-accessible storage. The data is encrypted using an encryption scheme that allows predictive analysis on the encrypted data without decrypting the encrypted data. The predictive analysis includes evaluation of polynomials of bounded degree on elements of the encrypted data. The evaluation includes ciphertext addition compositions and a bounded number of ciphertext multiplication compositions. The predictive analysis is performed on the encrypted data without decrypting the encrypted data to create encrypted results, which are transmitted to an entity possessing a decryption key capable of decrypting the encrypted results. | 04-18-2013 |
20140177828 | MANAGED SECURE COMPUTATIONS ON ENCRYPTED DATA - The subject disclosure is directed towards secure computations of encrypted data over a network. In response to user desired security settings with respect to the encrypted data, software/hardware library components automatically select parameter data for configuring a fully homomorphic encryption scheme to secure the encrypted data items while executing a set of computational operations. A client initiates the set of computational operations via the library components and if requested, receives secure computation results in return. | 06-26-2014 |
