Secure analytics using homomorphic and injective format-preserving encryption

Abstract: Secure analytics using homomorphic and injective format-preserving encryption are disclosed herein. An example method includes encoding an analytic parameter set using a homomorphic encryption scheme as a set of homomorphic analytic vectors; transmitting the set of homomorphic analytic vectors to a server system; and receiving a homomorphic encrypted result from the server system, the server system having utilized the homomorphic encryption scheme and a first injective, format-preserving encryption scheme to evaluate the set of homomorphic analytic vectors over a datasource.

Novel Encryption Method of GPS Information in Image File Using Format-Preserving Encryption

Abstract: Global Positioning System (GPS) information is stored in EXchangeable Image File Format (EXIF) in the image file. It is considered personal information; therefore, sharing it without the owner’s consent could lead to personal information disclosure. GPS information is embedded on the images uploaded by many people on social network services or stored in the Cloud. Images must be encrypted to prevent GPS information from being disclosed. However, there are no existing methods to encrypt them in EXIF. Using block cipher for encryption can exceed the tag value range of EXIF. In this paper, we propose a method to encrypt the GPS information of an image file using Format-Preserving Encryption, which preserves the length and format of the plaintext. We confirmed that GPS information can be secured by encrypting it in image files.

Self-Synchronized Encryption Using an FPE Block Cipher for Gigabit Ethernet

Abstract: In this work, a new solution for self-synchronized encryption in physical layer at Gigabit Ethernet optical links is proposed. The solution is based in the block cipher operating mode called PSCFB (Pipelined Statistical Cipher Feedback) using as underlying PRF (Pseudo Random Function) an FPE (Format Preserving Encryption) block cipher. Thanks to this structure is possible to encrypt 8b/10b Ethernet symbols preserving its coding properties at Physical layer in an optical Gigabit Ethernet interface. The IND-CPA (Indistinguishability under Chosen-Plaintext Attack) advantage is analysed for the first time concluding that this mode can be considered secure in the same way as traditional encryption modes are. In addition it provides self-synchronization while keeping an encryption throughput near 100%. Finally, the proposed mechanism has been simulated and synthetized in an FPGA (Field Programmable Gate Array) electronic device.

A Privacy-Preserving System based on Format-Preserving Encryption in Mobile Healthcare Environments

Abstract: Background/Objectives: The healthcare industry has been greatly grown based on the system such as EMR and HER. The objective is to prevent the privacy invasion in mobile EMR and HER healthcare environments. Methods: Token system is suggested to prevent the information used in healthcare mobile devices and it communicates with each mobile phone which operates as gateway as well as EHR and EMR. Findings: In this paper, healthcare device information token system is suggested based on the Format-Preserving Encryption (FPE) in the mobile healthcare environment for preventing personal information from being infringed while preserving availability in order to solve an aforementioned issue. Application/Improvements: Format-Preserving Encryption techniques have applications in Fintech, EMR, HER, bank, and credit card company
