FIELD: information recording for protection of products, goods, original articles against forgery. SUBSTANCE: composition for hidden information recording contains indicator solution in organic solution and developing composition. Solution A used in the capacity of indicator composition carries oxidation-reduction indicator selected from group including diphenylamine, sodium diphenylaminosulfate, phenylanthranyl acid and diphenylbenzidine. Invention describes method of hidden information recording by deposition of said indicator composition on substrate. EFFECT: simplified composition and method due to usage of easy-to-obtain reagents and exclusion of any devices for development of composition. 3 cl, 1 tbl
