Original: Advocating for the use of the key data source (generally known as the first document or initial data) for additional processing, discouraging alterations, or secondary resources. A duplicate of the first history needs to be formally verified as a true duplicate and distinguishable from the original.
Account for format considerations for example timezones and daylight price savings, particularly when combining data from several disparate resources.
Make sure that electronic signatures are legally binding and attributable to the person signing the history.
Defining the original Uncooked data results in being In particular crucial in the situation of computerized instruments. There is certainly frequently a huge distinction between the human readable Variation of the data (as an example, what’s offered for you about the monitor) and the particular Uncooked data being recorded.
「作業と同時に記録するよう徹底する」「基本作業者本人が記録する」「バックデートを禁止する」「記録が書き換えられないよう方針や基準で厳しく定める」「現場の時計を合わせる(紙媒体)」「入力端末の時刻などをタイムサーバに合わせる」「システムで改竄保証する」といった対応が必要。
Hybrid devices can be a little more challenging, because you'll want to think about the temporal and format disconnect among the file alone, the signature, as well as audit path.
Which means that the data is usually check here recorded at the actual time the action or do the job was performed. No piece of data must be recorded retrospectively.
Digitally recording data inside a file format with lasting compatibility retrieval aid helps to make sure data is out there from historian databases a long time right after it's recorded.
This dictates that the collection time of the data should really correspond on the date from the recording on the data.
Usually, nevertheless, contemporaneous data recording is yet another place which has a lot more relevance to manual history-holding. The leading goal is always to avoid website the practice of making or updating data eventually Down the road.
Build robust metadata monitoring and audit trail mechanisms, like Digital signatures with day and time stamps and watermarked goal proof, for clear data monitoring.
Furthermore, it's very simple to propagate glitches or normally unintentionally adjust information or their metadata whilst copying.
Consider every single new computerized technique for its raw data formats and compatibility. Ensure it is a part of the demands placing and First evaluation with the program.
While the act of attribution does feel uncomplicated, what you don’t want is for employees to own to guess, on the fly, which data details need dated signatures.
