Abstract: Systems and methods are disclosed for performing access control method by running a security software service as a localhost web service on an endpoint device; communicating with a system web server which manages licensing of the system and authentication of the endpoint device; creating a secure digital capsule that is controlled and can only be accessed by the system web server which authenticated the user and authorized the endpoint device; and placing on a distributed ledger messages and data files stored in the system in the secure digital capsules to detect and prevent alteration or manipulation of data.

Abstract: A magnetic stripe card provides a quantitative tool for the measurement of magnetic sensitivity for fine-grained iron, iron oxide or other ferro-magnetic powders, that may be used for magnetic particle inspection and other purposes. The magnetic stripe card is encoded to establish distinct areas on the magnetic stripe. Each distinct area has a specific magnetic gradient. Ferro-magnetic powders are attracted to the gradient in proportion to the value of the gradient. A higher gradient more strongly attracts the powder. A determination of the sensitivity of the powder can be ascertained by observing the gradient with the lowest value to which the powder is attracted.
