A method for performing data analytics on outsourced data may include receiving, at a data analyst, cipher text representing data from a data owner such that the data remains hidden from the data analyst, generating a query token using a constant provided by the data analyst such that the constant remains hidden from the data owner, and analyzing the cipher text using the query token.

Searchable encryption for outsourcing data analytics

A method for use with a spreadsheet includes storing a cell object, where the cell object includes a location in the spreadsheet of a cell to which the cell object relates and a process associated with the cell, and performing the process on a complex object to produce a result, where the complex object includes a construct comprised of data and code. A display is generated for the cell that is based on the result.

Adapting a spreadsheet for use with a complex object

Embodiments include a system for processing logical clock values according to a secure maximum operation. The system may include a communication unit and a processing unit. The communication unit may be configured to receive an encrypted first value of a logical clock, send an encrypted blinded difference, receive an encrypted blinded maximum value, and receive a maximum value. The processing unit may be configured to access an encrypted second value of the logical clock, generate the encrypted blinded difference between the first value and the second value, provide an encrypted blinded first value and an encrypted blinded second value in an oblivious transfer protocol, and generate an encrypted maximum value from the encrypted blinded maximum value.

Secure logical vector clocks

A system may include a gateway that is configured to intercept messages being exchanged between multiple services, a message repository that is logically coupled to the gateway and that is configured to store the intercepted messages, a service description repository that is configured to store multiple service descriptions, where each of the service descriptions corresponds to one of the services, a rules repository that is configured to store mapping rules and an adaptation engine that is configured to generate a sequence of firing rules using the service descriptions and the mapping rules responsive to the intercepted messages, to generate one or more outgoing messages in response to the intercepted messages using the sequence of firing rules, and to detect at runtime an occurrence of a termination anomaly.
