Abstract: A computing method for privacy-preserving data analysis is provided, in which the computing method is performed by at least one processor and includes receiving a data analysis request including data-to-be-analyzed from a client, homomorphically encrypting the data-to-be-analyzed using an encryption engine, and uploading the homomorphically encrypted data-to-be-analyzed to a target path of a blockchain, and then, the method includes, based on the request to check analysis result, decrypting an analysis result of the homomorphically encrypted data stored in a designated path of the blockchain by using the encryption engine, and providing the decrypted analysis result to the client, in which the analysis result of the homomorphically encrypted data is data analyzed by a worker linked to the blockchain, and stored in a designated path in association with the target path of the blockchain.

Abstract: Provided is a path-token-based web service caching method including determining whether or not stored cache data exists when a web service call request exists, and when the cache data does not exist, creating a predetermined path-token set and a predetermined tag data set based on a message schema of Web Services Description Language (WSDL), and creating a request Simple Object Access Protocol (SOAP) message, creating a request SOAP message template by using a path-token for the created request SOAP message, and calling the web service, and creating cache data including the tag data set, input values set, the request SOAP message template, the request SOAP message, and SOAP binding information. Accordingly, the method can solve the problems of a conventional web service caching method whereby the method can not cope with change in the number of inputs, and an exact input position is not searched for when an input value is changed.

Abstract: A system and method for aborting web services automatically. An application program container has a first web service application program embedded, intercepts a message that is transmitted and received between a second web service program located externally and the first web service application program, identifies the kind of an operation requested by the second web service application program, and keeps information required for compensation. A protocol manager generates and manages a first sub-transaction object by a request of the second web service application program. A local compensator compensates the first sub-transaction if a global transaction coordinator sends a command to compensate a second sub-transaction already committed. A protocol service unit transmits and receives messages for managing the first sub-transaction. A registration service unit registers the generated first sub-transaction with the global transaction coordinator.

Abstract: Disclosed is a method for creating and verifying SOAP messages in web service security using signature encryption. The SOAP message sender encrypts a signature used for SOAP message security with a secret key for encrypting data to be contained in the SOAP body. The encrypted signature is inserted in the security header of the SOAP header and sent to the recipient. The SOAP message recipient decrypts the encrypted key with his/her private key and restores the secret key. The restored secret key is used to decrypt the encrypted signature in the security header of the SOAP header, and the decrypted signature is used to verify the SOAP message.
