Oblivious Tensor Evaluation

Definition

Oblivious tensor evaluation is a cryptographic method for computing functions on multi-dimensional data without revealing the inputs. This advanced technique permits secure computations over tensors, which are multi-dimensional arrays, in a manner that conceals the specific data values from the computing parties. It is particularly relevant for privacy-preserving machine learning and complex statistical analysis in distributed settings. The process ensures that intermediate and final results are derived without exposing sensitive information.
