The present invention provides a method and system for securely transferring data over a computer network. A first party's computer: parses vulnerable words and numbers of a data set providing information for a second party, generates masked values of the parsed vulnerable words and numbers, updates the data set by replacing the vulnerable words and numbers with the masked values, and sends the updated data set to a third party for analysis, and for subsequent decoding, by the second party, of the masked values of the parsed vulnerable words and numbers. The first party's computer generates a first, second, third and fourth symbol of the masked values of a parsed word by: incrementing a first symbol of the parsed word by one, decrementing a second symbol of the parsed word by one, decrementing a second symbol of the parsed word by one, and inserting a predetermined marker symbol, respectively.

Securely transferring data over a computer network

According to an embodiment of the present invention, a system dynamically optimizes a service workflow including one or more software services. Initially, the system receives a request to optimize a service workflow, wherein the request includes one or more service requirements and one or more performance objectives related to the one or more service requirements. The system validates service plan information associated with at least one software service plan offered by one or more service providers and generates a plurality of candidate workflows based on the service requirements and performance objectives. The system then determines an optimized workflow from the candidate workflows and executes the optimized workflow to perform operations of the software services. Embodiments of the present invention further include a method and computer program product for dynamically optimizing a service workflow including one or more software services in substantially the same manner as described above.

Optimization of a workflow employing software services

Embodiments of the present invention disclose a method, computer program product, and system for detecting changes in database schema. The embodiments may include receiving a first database schema. The embodiments may include creating a first value corresponding to the first database schema by utilizing a compressed value algorithm. The compressed value algorithm may create a single value corresponding to each database schema. The embodiments may include receiving a second database schema. The embodiments may include creating a second value corresponding to the second database schema by utilizing the compressed value algorithm. The embodiments may include determining whether there is a difference between the first database schema and the second database schema by comparing the first value and the second value.

Database comparison system

The present invention provides a method, and associated computer system and computer program product, for masking selected vulnerable data portions of a data set transmitted over a network by parsing the vulnerable data, generating masked values for the vulnerable data including generating symbols of the masked values of a parsed word of the parsed vulnerable data, updating the data set to include the masked values, then sending the updated data set to a third party for analysis and for subsequent decoding of the masked values of the parsed vulnerable data. The symbols, used to represent basic sounds of a language, are contained in a set in a fixed order.

System and method for securely transferring data over a computer network

A plurality of subgroups of identifiers are identified including at least a first subgroup of identifiers and a second subgroup of identifiers within an identifier range. A first set of identifiers is selected in the first subgroup. The first set of identifiers in the first subgroup is compared with a second set of identifiers in the second subgroup and a first set of common identifiers is identified using metadata of the second set of identifiers. A third set of identifiers is generated by eliminating the first set of common identifiers from the first set of identifiers. The third set of identifiers is compared with a fourth set of identifiers in a repository of stored identifiers, to identify a second set of common identifiers. A fifth set of identifiers is generated by eliminating the second set of common identifiers from the third set of identifiers.

Allocating unique identifiers using metadata

A method, a system, and a computer program product for creating a set of identifiers are disclosed. A first set of identifiers is generated by a first randomization of a partition. Identifiers of the first set of identifiers are selected to generate a third set of identifiers. A second set of identifiers comprising a pre-defined number of identifiers is generated by a second randomization of the third set of identifiers.
