Provided is a system and method for confidential string-matching and confidential deep-packet inspection. The method includes: receiving encrypted ciphertexts from a first computing device; windowing a text corpus and applying a hash; performing binning and splitting on the corpus set of hashes; performing batching on the binned and split corpus set of hashes; determining match ciphertexts by evaluating a homomorphic encryption circuit between the encrypted ciphertexts and the batched corpus set of hashes; and communicating the match ciphertexts to the first computing device, the confidential string matching determinable by the first computing device by: decrypting the match ciphertexts, determining from the decryption output, if the hash value for each pattern window matches the hash value for any corpus windows and if the matched windows are adjacent in the corpus.
