METHOD AND SYSTEM FOR KEEPING DATA SECURE

摘要

The present disclosure provides a method and system for keeping data secure. The method includes: acquiring at least one audio signal and assigning the segment to an audio frame having a predetermined size; partitioning the data to be kept into a plurality of portions with a maximum capable bit the data kept in each of the sampled points;;transforming the partitioned portions of the data into different frame sizes; framing each of the audio frames according to the plurality of frame sizes transformed; calculating an average value of the points in each frame, replacing a value of a first point within each frame with average value. The present disclosure can effectively resist noise jamming and bit replacement attacking.

1. A method for keeping data secure in audio data, comprising:
acquiring at least one segment from an audio signal and assigning the segment to an audio frame having a predetermined size, the audio frame comprising a plurality of sampled points; partitioning the data to be kept into a plurality of portions with a maximum capable bit the data kept in each of the plurality of the sampled point; transforming the partitioned portions of the data into different frame sizes; framing each of the audio frames according to the plurality of frame sizes transformed; and calculating an average value of the points in each frame, and replacing a value of a first point within each frame with average value.
