And is encrypted by a predetermined procedure described later and stored in a desired storage unit 4 such as an FD, an MO, or an HDD. In addition to the display, the recording means 5
Digital printing and analog recording can be performed. Then, the encrypted data is decrypted again by the processing means 2, and
Can display, record and confirm.

お、これらの処理は、処理手段２で実行される。That is, as shown in FIG. 1B, the operation of the processing means 2 shows that the data which has been fetched by the input means 1 is displayed on the display means 3 to be displayed and encrypted. . For example, in the case of the original data of "123.45", if it is multiplied by 8 and arranged in reverse, it becomes "6.789", and the checksum of this encrypted data is "30".
Then, it is stored in the storage means 4 together with the check code. Then, each measurement data is sequentially encrypted and stored in the storage unit 4 together with the check code. When necessary, each of the encrypted data and the check code stored in the storage means 4 is decrypted, the original data is restored, and the recording means 5 is subjected to a printing process to be printed by the recording means 5 or a display process is performed. It can be displayed on the display means 3 and stored in another storage means and used for certification. These processes are executed by the processing unit 2.

＝Ｄ］となる。That is, if the encrypted data is used as it is, it becomes different from the original data, and cannot be used as guarantee data as it is, thereby preventing misuse. Further, since the check code is generated from the encrypted data, if the data is changed, it is immediately determined, and the change can be prevented. In other words, at the time of decryption, based on the check code, a check code is created from the encrypted data, and if it matches the stored code, decryption is performed,
If they do not match, it is determined that data has been altered. Then, the information that this data is abnormal is notified to the outside, and an appropriate measure is taken that the data has been altered. For example, the original data is D, the encryption function is F, the check code is C,
If the decryption function is G, the stored encrypted data is
Decoding this with [F (D), C] gives [GF (D)
= D].

A measurement data storage device stored in the storage means and decrypting the encrypted data and the check code stored in the storage means. That is, if the encrypted data is used as it is, it becomes different from the original data, and it is possible to prevent the encrypted data from being used as guarantee data. Also, since a check code is generated from this encrypted data,
If data has been altered, it is immediately identified and alteration can be prevented. That is, at the time of decryption, a check code is created from the encrypted data based on the check code, and if it matches the stored code, decryption is performed, and if not, it is determined that the data has been altered. In this way,
Data reliability can be ensured, and data modification and the like can be handled. In addition, since the data can be stored in electronic data, the storage space is small, the storage and handling are easy, and it is useful for quality assurance, quality certification, inspection report and the like.
