Abstract: A method of executing an instance of a smart contract through a blockchain shared among a plurality of nodes including the following first step of serializing in the blockchain of the instance of the smart contract, and the following steps in cyclical succession: a second step of serializing a plurality of status files each containing a state defined only by internal variables of the instance at an end of a respective plurality of executions of the instance, the plurality of status files are temporally ordered according to the respective plurality of executions of the instance, a third step of deserializing in a RAM of a last state of the instance by deserializing at least one last state file from the blockchain, and a fourth step of deserializing the instance by valuing a second state of the instance as a last state, a fifth step including further execution of the instance.

Abstract: A remote wipe message or notification may be sent from a server computer to one or more target client devices associated with a user. A managed container running on a target client device associated with the user and having a managed cache storing content managed by or through the server computer may, in response to the remote wipe message or notification, deleting the managed content or a portion thereof from its managed cache. The managed container may send back an acknowledgement or message to the server computer that it had completed the remote wipe. The remote wipe functionality can avoid having to deal with individual applications running on the client device and therefore can eliminate the complexity of having to deal with individual applications. Furthermore, the remote wipe can be done independently of the local operating system and without affecting non-managed information/applications on the client device.

Abstract: A computer implemented method for securing at least one of files and records related to a specific process, the method comprising obtaining interaction data comprising one or more persons and one or more files and/or records, said interaction data comprises a process interaction score between at least one user and the specific process; identifying, from the interaction data, one or more persons and one or more files and/or records related to the specific process; comparing a process threshold with a process interaction score between a target user and the specific process; and in response to the comparison satisfying a rule, performing a security operation on the one or more files and/or records related to the specific process.

Abstract: A method of authenticating a user of a multifunction device to a server, the method comprising associating a user-supplied image with user login credentials, using a server; receiving, at the server, an image uploaded from the multifunction device; and comparing the uploaded image to the user-supplied image, using the server, and, only if the uploaded image matches the user-supplied image, allowing the user of the multifunction device to authenticate to the server by providing additional login credentials to the server using the multifunction device.

Abstract: A computer system controls access to data. A request is received from an entity to access data comprising a primary data object corresponding to a physical item. One or more secondary data objects included in the primary data object are identified, wherein the one or more secondary data objects correspond to physical components of the physical item. Access requirements for the primary data object and the one or more secondary data objects are determined. In response to determining that the access requirements are satisfied by the entity, the entity is granted access to the data comprising the primary data object and the one or more secondary data objects. Embodiments of the present invention further include a method and program product for controlling access to data in substantially the same manner described above.

Abstract: Aspects of the invention include receiving a data erasure request associated with a user and identifying, based at least in part on the data erasure request, an entity associated with the user and one or more identifiers for the user. Aspects also include identifying, based at least in part on the one or more identifiers for the user, a cohort that includes the user and comparing the one or more identifiers for the user to identifiers of a plurality of users that are not members of the cohort. Aspects further include identifying a replacement user from the plurality of users based on the comparison and replacing the entity associated with the user in the cohort with an entity associated with the replacement user.

Abstract: The present invention relates generally to broadband, reflective circular polarizers and, more particularly, to single layer super broadband, reflective circular polarizers. The polarizers of the present invention are made from a film of material, like a polymer having a cholesteric order, in which a second liquid crystal material, like a nematic liquid crystal, is distributed in a non-linear fashion across the thickness of the film in a plurality of liquid crystal-rich and liquid crystal-depleted sites in the polymer. The resulting polarizers have band passes approaching 2000 nm and reflect circularly polarized light which is either left-handed or right-handed depending on the final spiral structure of the materials utilized. The material of the present invention is fabricated by mixing commercially available polymers having a cholesteric order, a second liquid crystal material and a photoinitiator at a temperature which maintains the mixture in a liquid state.
