Fake and Real Massaging at the Same Time with QR Code in Web Services for Different Users

Table 1

Testing environment change and implementation strategy.

Test Environment Variable	Application Strategy
The number of clients for the test environment is related to the job size	More work should be done for the same workload as possible per client.
Relationship of a hash algorithm for test environment	The SHA512 algorithm can be selected.
The hash algorithm for the test environment QR code size relation	The lowest QR code should be preferred whenever possible.
Image layer relationship for test environment	If the number of layers is selected a lot, the working time is very long, so it can be used as a choice between low numbers.
Text size for unencrypted test environment the content of the related descriptions includes the length of the subtext, the length of the upper text	The effect of the length of the top and bottom text on the duration of the study is insignificant. This feature can be used because variable length selection affects hash value.
The text size relationship for the encrypted test environment, the length of the contents of the description subtext	It has the same conditions as the free environment. As a difference, there is a period of irregular working which comes from the encrypted environment itself.
