Abstract: In some examples, with respect to zone based key version encoding, data that is to be encrypted may be ascertained, and a key, including a key version, that is to be used to encrypt the ascertained data may be ascertained. Encrypted data may be generated by encrypting the ascertained data based on the ascertained key, and a zone representing the key version may be determined. Further, encrypted zoned data may be generated by applying the determined zone to the encrypted data to encode the key version, and the encrypted zoned data including the encoded key version may be stored.

Abstract: In some examples, with respect to hash offset based key version embedding, data that is to be encrypted may be ascertained, and a key, including a key version, that is to be used to encrypt the ascertained data may be ascertained. Encrypted data may be generated by encrypting the ascertained data based on the ascertained key, and hashed encrypted data may be generated by performing a hash operation on the encrypted data. Further, offset hashed encrypted data may be generated by embedding the key version into the hashed encrypted data, and the offset hashed encrypted data including the embedded key version may be stored.

Abstract: In some examples, geographical track data obfuscation may include ascertaining geographical data points that include a first data point and subsequent data points. For each of the subsequent data points, a delta degree value may be determined as a difference between a subsequent data point and a corresponding previous data point. A first format preserving encryption (FPE) may be applied to encrypt longitude and latitude values of the first data point. A second FPE may be applied by applying a translation of a plurality of translations to encrypt each delta degree value. A total distance traveled, a total time, and/or a total elevation gain may be extracted from the encrypted first data point and the encrypted delta degree values.
