Patent ID: 8596522

Claim:
A method for constructing and composing, on at least one sheet, at least one identifier on the basis of at least one sampling of at least one cell in at least one page obtained from a general pattern, wherein said at least one sheet comprises a patterned content zone on which the hand of a user writes or makes graphical signs, said content zone is obtained by at least one sampling of at least one cell of said at least one page and wherein reading of said identifier is performed by means of a digital writing and reading instrument associated with said at least one sheet, said method comprising the steps of: defining n “master” pages P having the address “P(ai)” (wherein 1<i<n), each divided into n1 cells “C(I) (wherein 1<I<n1)” so as to form at least one part of said identifier by sampling of said at least one cell; defining a special master page having the address “P(a 1 )” dedicated to the beginning of each identifier, in which there is sampled one cell “D” of the beginning of each constructed identifier; defining a special master page having the address “P(a 2 )” dedicated to the end of each identifier, in which there is sampled one cell “F” of the end of each constructed identifier; defining m “slave” pages “p” having the address “p(bj)” (wherein 1<j<m), each divided into m1 cells “c(J)” (wherein 1<J<m1) to form each content zone of each writing surface by sampling and grouping; inserting, for a given sheet, between said first cell “D” and said last cell “F” of each identifier, a cell c(J) sampled in a slave page “p” whose address is identical to that of cells c(J) serving to constitute said content zone belonging to said given sheet; inserting, for other cells C(l) of said identifier, which are neither said cell “D” said cell “F”, nor said cell c(J), an address or addresses “P(ai)” in random manner or according to an algorithm; choosing, for said cell c(J) of said identifier of said given sheet, and for all cells c(J) comprising said content zone of said given sheet, an address “p(bj)” in a random manner or according to an algorithm; acquiring said identifier by passing said digital writing and reading instrument over all of said cells of said identifier; using said content zone by writing with said digital writing and reading instrument in said content zone on said patterned paper so as to achieve a writing result; sending said writing result in the form of a succession of data to an IT processing unit; and filtering and processing said data corresponding to said writing result before final use thereof.
