摘要:
The present invention is directed to a method for detecting unwanted executables and preventing the damage thereof, comprising: defining at least one API call as suspicious; scanning an executable for detecting suspicious API calls; and upon detecting a suspicious API call within said executable, either just determining said executable as unwanted or inspecting said executable. Following inspection, if said executable is indicated as unwanted and/or malicious, the damage thereof is prevented by eliminating the suspicious calls from said executable, discarding said executable, etc.

A method for indicating the integrity of the use-information of a program, comprising: providing a mechanism based on the state of a marker file (being one or more files dedicated especially for this purpose) for generating upon request an asymmetric (i.e. can be read by a user but cannot be altered by him) and unique or pseudo-unique value; instructing the mechanism to generate a value; sealing the use-information with the generated value; and indicating the integrity of the sealed data by the correspondence of the stored value with the current value returned by the mechanism. In a preferred embodiment of the invention, the information is stored in a secure manner (e.g. encrypted, digitally signed, and so forth). The invention may be implemented in any licensing model in which the use-information is important, like a Try before you Buy model, renting a program, and so forth.
摘要:
A method for hiding information on a computer, comprising: storing said information in one or more storage entries (e.g. file, registry entry), having a name that is derived in a secret manner from the identity (e.g. serial number) of one or more computer components. According to a preferred embodiment of the invention, deriving a name in a secret manner from the identity of one or more computer components is carried out by: generating a pseudo-random sequence, the seed of said sequence derived from the identity of said one or more computer components; and deriving a name from one or more value of said pseudo-random sequence. The computer components may be hardware and/or software modules, e.g. CPU, a computer chip, a computer program, the BIOS, a file (the name of a file, the ID of a file, the physical location of a file), the volume name of a disk, etc.

摘要:
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.

The present invention is directed to a printed circuit board, comprising: at least one chip; and a board comprising at least one aperture corresponding to each chip, for enabling each chip to be placed inside the corresponding aperture, thereby enabling reducing the thickness of the printed circuit board to that of the thickest chip. According to one embodiment of the invention, the chip is placed on the board with the upper side of the chip up. According to another embodiment of the invention, the chip is placed on the board with the upper side of the chip down. According to one embodiment of the invention the legs of the chip have “straight” form. According to another embodiment of the invention the legs of the chip have “bent” form.
摘要:
A method for blocking Spam sent to an email address of an individual, comprising: establishing an intermediating email address, for corresponding with a party of interest without revealing the permanent email address of the individual; indicating an email message sent to the intermediating email address as Spam unless the sender thereof is the party of interest. On indicating an email message as Spam, blocking the email message. On indicating an email message as non-Spam, redirecting the email message to the permanent email address of the individual. In one embodiment of the invention, the intermediating email address expires after a predefined or arbitrary period. The method may be implemented by an email client associated with the intermediating email address, an email server, a proxy server, a gateway server and so forth.

摘要:
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.
