A random number-based method for distributively storing, mixing, and repeatedly extracting/dividing data is provided to make the recovery of an illegally leaked portion of data or the whole data impossible in the case of entrusting the data to the third computer through a communication network. A random number-based method for distributively storing, mixing, and repeatedly extracting/dividing data comprises the following steps of: receiving important information of a user and a password from the user(12); generating random numbers(14); mixing the user's important information based on the generated random numbers(16); dividing the mixed information into the 'n' number of pieces(18); integrating the divided information pieces into one information based on the random numbers(22); and rearranging the combined information based on the random numbers to restore it to the original important information(24). |
