Description of the invention (2) In order to reduce the personal storage of one person, the data keeper shall receive one additional person ’s private information, and then encrypt the key, the confidential information, and the portable individual. In addition, the portable personal computer will receive the case. . Next, a decryption key is entered into the combination of answers to the questions in the private storage. The storage can be media. The diagram simply states that in order to make the following specific cost-encryption technology, the basis for the problem of confidential information is to treat individuals with this much privacy as the person ’s privacy should be based on this. The bank ’s decryption example is discarded. In. It is an embodiment of the invention of the IC card, which achieves the above purpose. First, set the encryption and decryption rules of the combination prompt. Private information is stored in the 4 question combination memory. The combination of the weighting problem combination encryption and decryption rules in the portable personal storage is stored in the portable type, so that it can be included without further recording. Re-question, multiple lines of encryption, prompts and secret storage take one of multiple reminders, so that multiple people are private and one person is privately encrypted with the system's main embodiment or other texts, when the group of questions The private solution to the problem is to repeatedly ask the storage secret decryptor or cocoa invention to provide a portable personal reminder, and combine the answers, and the combined answer is-when you get a ciphertext private data stored in the secret, first The combination prompts, but the combination of questions and answers is the body of the body-cipher text. The multiple questions of use are portable personal, portable personal privacy, portable storage, and the above purpose, combined with the attached features and excellent icons, make it more detailed and easier to explain as follows

Referring to FIG. 3, the inventor's method for making a portable personal private storage by Erguren will be described as follows. Only the example of system 1222304 is used. V. Description of the invention (6) Same) 'and as in step S2 1 0, the user sets a multiple question combination answer corresponding to one of the multiple question combination prompts. In addition, the system also proceeds to step S220 to receive one of the user's private data that the user wishes to encrypt and protect. 0 Next, in step S230, the multiple question combination answer is used as an encryption key 4 and according to the encryption key, the personal data of the user who wants to be encrypted is encrypted to obtain a ciphertext private data. Finally, in step S240, the multiple question combination prompts and the ciphertext private data are stored in a personal privacy storage that can be used. Similarly, in this embodiment, after the personal private information is encrypted, the multiple question combination answers used for encryption are discarded. , Household riding diagrams-shows the portable personal private storage according to the embodiment of the present invention. Among them, the portable personal private storage 1 000 sets of pre-set data, one is the plain text data 1100, which refers to the combination of the user's deduplication questions, and the other is the cipher text data 1200, which refers to the private data. : Encrypted ciphertext of personally protected personal data: Portable personal privacy storage can be 1C card, magnetic disk can be portable storage media. Decryption of Portable Personal Private Storage> Personal Private Γ Dense Map: Stream Display Process: According to Figure 5 of the Portable Personal Private Data, the embodiment of the present invention will explain the processing of the fork as follows. -Multiple question combination tips, and; c read in private storage (not shown). Then, the prompt question combination prompt is displayed, as shown in step S260, receiving 1222304 input by the user. V. Description of the invention (7) ^ Corresponding to this multiple question combination, the user is provided with the step S 2 7 0. Key, and according to the decryption of one of the ciphertext private information departments in the mining industry, similarly, in this embodiment Θ this multiple questions used to decrypt the multiple questions Zhao combined into answer and use simultaneously, you can If the ciphertext is privately owned, the ciphertext private information cannot be used in the above embodiment. The storage can be made by using a personal computer and a portable device such as a card reader and a 1C card burner. By using the combination of problems described in the present invention, the private data is stored in the user's personal password and personal private data. The security and security advantages of the private data are as follows: Μ First, the user is allowed to use the user Easy to remember, in addition, it is not easy to be tried and error. Second, the encryption and decryption keys can be stored in a fixed storage, and can be used after nearly two secrets. The reading of a single processing unit is ν > wood encryption technology, which can be used in the body, with a clearer and more complex problem set. Multiple question set answers will be stored in a portable decryption. The ciphertext private S data solution answer is discarded. The user's previously set material is decrypted into plain text and restored to the original setting and read (decrypted) to handle basic operations. Personal private storage, or personal data from disk drives, etc. is guaranteed to be encrypted or decrypted. Storage media is required in the system host. At the same time, this secret question is used as a solution because the key data method is used to break it; discard it after use, and the personal private answer will not be added. As a decryption of personal private storage, it ’s exactly what the user entered; anti-data. Personal secrets ’such as writing 〇’ can be used to strengthen the individual without the need to strengthen the following key entry, the length is not fixed, need to be stored in the security of certain data
