Mobile-to-mobile transactions
A mobile-to-mobile transaction method allows two mobile smartphones to engage in a private transaction between themselves. The two share the same transaction server using prearranged individual enrollments. These build a dynamic digital image of a colorgram with a selected shape that defines a colorgram matrix boundary. Authentication codes, merchant coupons, product advertisements, and browser uniform resource locator (URL) links for product information and ordering, one-time-password (OTP) seeds, initialization vectors, individual enrollment passwords, or password seeds are embedded and encrypted in each colorgram. The colorgram is sent to a first one of the mobile smartphones for its display to a collocated second one of the mobile smartphones. A transaction is authenticated between users based on a calculated expectation of what should be returned when it provides its own digital image of the colorgram displayed by the first mobile smartphone.
1. A mobile-to-mobile transaction method, comprising the steps of:
logging at least a first and a second mobile smartphone onto a common transaction server over a network with a user preregistration data;
building a dynamic digital image of a colorgram at the common transaction server based upon said user preregistration data and including a selected colorgram matrix boundary shape;
embedding in and encrypting each dynamic digital image of a colorgram with at least one of a user authentication code, merchant coupon, product advertisement, browser uniform resource locator (URL) link for product information and ordering, one-time-password (OTP), initialization vector, individual enrollment password, and password seed;
sending the dynamic digital image of a colorgram after building, embedding, and encrypting from the common transaction server to the first mobile smartphone for its display to and observation by the second mobile smartphone;
observing the display of the first mobile smartphone with the second mobile smartphone, and returning a facsimile of it to the common transaction server;
authenticating with the common transaction server a proposed transaction between the first and second mobile smartphones based in part on a calculated expectation of what the second mobile smartphones should return as said facsimile; and
completing the proposed transaction if the step of authenticating succeeds, and sending confirmations of a completed transaction to each of the first and second mobile smartphones;
wherein, said proposed transaction authentication is more secure and less subject to fraud before completion.
2. The mobile-to-mobile transaction method of claim 1 , further comprising the steps of:
selecting said colorgram matrix boundary shape;
wherein, a selected colorgram matrix boundary shape presented by the common transaction server is recognizable as one that was previously selected; and
wherein, a recognition and acknowledgement of the selected colorgram matrix boundary shape presented by the common transaction server operates as a means for authentication.
3. A mobile-to-mobile transaction device, comprising the means for:
logging at least a first and a second mobile smartphone onto a common transaction server over a network with a user preregistration data;
building a dynamic digital image of a colorgram at the common transaction server based upon said user preregistration data and including a selected colorgram matrix boundary shape;
embedding in and encrypting each dynamic digital image of a colorgram with at least one of a user authentication code, merchant coupon, product advertisement, browser uniform resource locator (URL) link for product information and ordering, one-time-password (OTP), initialization vector, individual enrollment password, and password seed;
sending the dynamic digital image of a colorgram after building, embedding, and encrypting from the common transaction server to the first mobile smartphone for its display to and observation by the second mobile smartphone;
observing the display of the first mobile smartphone with the second mobile smartphone, and returning a facsimile of it to the common transaction server;
authenticating with the common transaction server a proposed transaction between the first and second mobile smartphones based in part on a calculated expectation of what the second mobile smartphones should return as said facsimile; and
completing the proposed transaction if the step of authenticating succeeds, and sending confirmations of a completed transaction to each of the first and second mobile smartphones;
wherein, said a transaction authentication is secured and less subject to fraud; and
wherein, fraud may be preempted before a transaction can complete.
4. The mobile-to-mobile transaction device of claim 3 , further comprising means for:
selecting said colorgram matrix boundary shape;
wherein, a selected colorgram matrix boundary shape presented by the common transaction server is recognizable as one that was previously selected; and
wherein, a recognition and acknowledgement of the selected colorgram matrix boundary shape presented by the common transaction server operates as a means for authentication.
