Abstract: What is provided is a method of adding a functionality to an executable first module of a program package, wherein the executable first module, during execution, provides an internal function or utilizes an internal function of an executable second module of the program package; wherein, when the first module is not executed, an externally visible reference pointing to said internal function is determined, auxiliary code is added to the first module and a redirection is permanently provided in the first module as a function of the reference thus determined such that a modified executable first module is present, wherein, when the internal function is requested during execution, a redirection is made to the auxiliary code which causes the functionality to be provided during execution.

Abstract: An efficient symmetrical-cryptographic method for using a fast but insecure host to perform encryption/decryption based on a secret key in a secure, but slow hardware token, such as a smartcard or similar device, without revealing the secret key to the host, and such that the ciphertext and plaintext are exactly the same size. The present method is suitable for use in Digital Rights Management and Software Rights Management applications which require precise interchangeability of ciphertext and plaintext in pre-allocated areas of data storage.

Abstract: A method and system for issuing and redeeming digital coupons for requesting and granting modifications of licensed computer data products. Modifications include versions and configurations of the licensed data product as well as licensing issues related thereto. A product licensor issues authenticated coupons to customer organizations which utilize the licensed data products. The coupons are not necessarily specific to any particular computer or device, data product, version, license or configuration. Coupons can thereby be easily distributed to users within the organization. A user fills out the coupon with a request for the desired modifications and sends the coupon to the licensor, who fulfills the request by sending modification installation code directly to the user, thereby avoiding unnecessary overhead burdens on the organization. Digital coupons may be used in conjunction with external hardware devices (“dongles”) or with internal software licensing modules.

Abstract: A method and system of computer program modules for extending the cover time of protection for a licensed software product, by increasing the difficulty and time required for an attacker to produce a workable cracked version of the program. When an attack is detected, critical information about the effectiveness of the attack are withheld from the attacker by simulating the behavior of a cracked program, thereby inducing the attacker to prematurely consider the attack successful. Latent license enforcement features are provided, whose activation is suspended until predefined environmental conditions are met.

Abstract: A method for determining if a software program having a protective envelope has been cracked, and signaling an indication thereof. A direct determination is made of whether the protective envelope is intact or has been compromised by an attack, without requiring a license violation to occur. Executable code in the protective envelope generates an envelope confirmation which is validated by executable code in the program itself. Any disabling or separation of the envelope from the program will be detectable by the program at validation time. Provisions are made for a secure envelope confirmation, the use of arguments as input to the confirmation generation, and for incorporating information related to the computer and user to facilitate identifying the attacker. Signaled indications can include network messaging to alert the licensor that the program has been cracked.

Abstract: A method for issuing and updating a software program license for a computer, with a unique identifier data object embedded in the computer and referenced by the license. The unique identifier may also be used with a conventional computer fingerprint. The software program does not run on a computer without a license that references the unique identifier. The license is issued via a server over a network (such as the Internet) and must be regularly updated by the server. When updating, the present unique identifier is sent to the server, to verify that the unique identifier is the latest unique identifier issued for that license. If an unauthorized copy is made for operation on an unlicensed computer, such as by cloning the licensed computer, this is detected when the second computer is updated, because the unique identifier sent with the update request is no longer current.

Abstract: What is provided is a computer-implemented method for protection of a program comprising a functional block, wherein the functional block is encrypted, additional code is added to the program and a protected program is thus generated, which is executable only in the presence of a predetermined license in a computer system which comprises a working memory, into which the protected program is loaded during execution, and a protection module for protection against unauthorized execution of the protected program, wherein, if the encrypted functional block is to be executed during execution of the protected program, the additional code is executed and, if a license is present, said additional code, together with the protection module, a) causes decryption of the functional block such that the functional block is present in the working memory of the computer system in decrypted form; b) allows execution of the decrypted functional block, and c) upon completion of execution of the decrypted functional block, causes
