Authirization for a SAP Script Standard Text

Hi ,

I have a standard text and an image which i have uploaded into SAP and then I am displaying it in my form( SAP Script Layout ) my requirement now is to secure the Standard Text and Image from access to any one else.

Please tell me how will this be possible. ? Its pretty urgent . please help
