A method for checking edited text to track modification in text copied from a first electronic document, said method comprising: creating, by a processor of a computer system, a temporary computer object; said processor getting an address of said first electronic document; said processor copying said address of said first electronic document into a header of said created temporary computer object; said processor copying a first tag and a second tag into the header of said created temporary computer object, wherein the first tag marks the beginning of the header of said created temporary computer object, wherein the second tag marks the end of the header of said temporary computer object, and wherein the address of said first electronic document is disposed between the first tag and the second tag in said created temporary computer object; said processor copying text from said first electronic document into said created temporary computer object; said processor copying a third tag into said created temporary computer object, wherein the third tag marks the end of said created temporary computer object, and wherein said copied text is disposed between the header of said created temporary computer object and the third tag; said processor storing said created temporary computer object; after said storing, said processor ascertaining that a portion of text is removed from said copied text or is inserted in said copied text; in response to said ascertaining: said processor inserting said third tag at a first position where said portion of text is removed or at a second position preceding a third position where said portion of text is inserted; and said processor inserting a string at the first position where said portion of text is removed or at the second position preceding the third position where said portion of text is inserted, wherein said string is a concatenation of said first tag, an address associated to said copied text, and said second tag.
