This specification discloses devices and methods for a security concept that includes an immobile hardware token (e.g., a “wall token” that is fixed within a wall) which ensures that the more sensitive actions of electronic banking (e.g., money transfers of large sums to foreign bank accounts) can only be done from the account owner's home, but not from a remote place.

Privacy-enhanced decision tree-based inference on homomorphically-encrypted data
A technique for computationally-efficient privacy-preserving homomorphic inferencing against a decision tree. Inferencing is carried out by a server against encrypted data points provided by a client. Fully homomorphic computation is enabled with respect to the decision tree by intelligently configuring the tree and the real number-valued features that are applied to the tree. To that end, and to the extent the decision tree is unbalanced, the server first balances the tree. A cryptographic packing scheme is then applied to the balanced decision tree and, in particular, to one or more entries in at least one of: an encrypted feature set, and a threshold data set, that are to be used during the decision tree evaluation process. Upon receipt of an encrypted data point, homomorphic inferencing on the configured decision tree is performed using a highly-accurate approximation comparator, which implements a “soft” membership recursive computation on real numbers, all in an oblivious manner. |
