NEW METHODS FOR PROTECTING VITAL INFORMATION / COMMERCIAL PRODUCTS FROM
ILLEGAL USAGE / REPRODUCTION
Technical Field
This invention relates to new methods for protecting vital information
only known to concerned parties such as password, PIN, or credit card number
transferred over a network from being cracked by wire-tapping or some other
means, or software products or contents (music, images, etc) distributed
across a network or written on CD-ROM from illegal usage or illegal
reproduction (piracy).
Background
In the prior art, vital information such as password, PIN, or credit
card number is transferred over a network with no encryption (as is) or with
one of published or proprietary encryption techniques, with key(s) (public
key and private key; the former is known to anybody, and the latter is known
to each of concerned parties only), or without keys (such as in proprietary
one-time password generator), which are considered to be mathematical ly very
difficult to crack (i.e., taking a great amount of time to find the original
information). This is also true for software products or contents (music,
images, etc) transferred across a network or written on CD-ROM (e.g.
protection is carried out through a CD key printed on a label of each CD- ROM or no protec ion is provided at al I) or other conventional media. Most
of regular commercial software products and contents CD-ROMs are
protection-free to allow the pirate business.
Such pubI ished encryption methods include: CryptographicApparatus and
Method (U.S. Patent No.4,200,770), Publ ic Key Cryptographic Apparatus and
Method (4,218,582), Exponentation Cryptographic Apparatus and Method
(4,424,414), Cryprographic Communica ions System and Method (4,405,829), and
Method for Identifying Subscribers and for Generating and Verifying
Electronic Signatures in a Data Exchange System (4,995,082).
However, the prior art as such requires a great amount of computation
in encryption and decryption and may be subject to being cracked in some cases.
In addition, in order to improve security, the number of bits in a key must
be increased, which wouId further Iengthen thecomputation time and compI icate
the logic to implement the algorithm.
The information already known to concerned parties such as password,
PIN, or creadit card number need not be deciphered if the both parties use
the same encoding method.
Also, software products or contents can be protected from i I legal usage
or illegal reproduction by attaching special information which is only
enciphered for the same reason as above when both manufactured and used.
Hence, this inven ion uses any theoretical ly undecipherable encoding method based on the fractal theory to work around the possibility of being
cracked, whi le al lowing concerned parties to share vital information or to
use software products or contents, with drastical ly shorter computation time
and much simpler logic to implement the algorithm.
Disclosure of Invention
The present invention uses any theoretical ly undecipherable encoding
method based on the fractal theory. In general , any. of such methods is used
mainly for image compression (because they were invented for such purpose),
which are proved not to be completely decoded (there is no way to restore
complete original images; Ref. Fracta/ /mage Compress ion Theory And
Application Editor Yuval Fisher, published by Springer-Verlag, 1994). In
the present invention, this nature of the fractal encoding is applied to
protecting vital/commercial information from illegal usage or illegal
reproduction, whereby only concerned parties, who are permitted to know or
use vital information, or software products or contents, can apply the same
method to encode the same information to get the same result (there is no
decoding process involved), whi le providing no clues to this information to
thosenot concerned, unless of course they happen to know thevital information
by some other means I ike a simple guessing, eavesdropping, overlooking, or
threatening any of which is beyond the scope of the present invention.
THIS TYPE OF APPLICATION OF THE FRACTAL ENCODING METHODS TO THE PROTECTION OF VITAL INFORMATION/COMMERCIAL PRODUCTS IS TOTALLY NEW ANDUNIQUE
TO THE PRESENT INVENTION.
Best Mode of Carrying Out the Invention
The present invention is provided as a software program such as a DLL.
It may also be implemented as a firmware. Several embodiments of the present
invention are disclosed herein.
First, vital information such as password, PIN, or credit card number
transferred over a network can be protected by using the same encoding method
based on fractal theory on both ends (sender and recipient). In this case,
vital information wi 11 be encoded along with other known information such as
a timestamp or a certain predefined one-time data to avoid anybody else's using
the encoded information as aval id transaction. This invention is useful for
user authen ica ion, electronic banking, and electronic commerce. An example
fo11ows:
(1) 'Center' sends 'Enter Password:'+timestamp to 'Terminal'.
(2) 'Terminal' returns Password+timestamp encoded with the present invention.
(3) 'Center' encodes stored password+timestamp and checks if the received
encoded password+timestamp matches this encoded password+timestamp with the
present invention.
(6) If they match, password proves correct. Otherwise, password proves
incorrect. Secondly, commercial software products or contents distributed across
a network can be protected from i I legal usage (I ike as freeware) or i I legal
reproduction (piracy) by a recipient, by using this encoding method to
generate media-unique information on the media where products or contents are
installed (downloaded). The generation of media-unique information may be
achieved upon registration or I icense provision (without it, the products or
contents should be disabled). An example follows:
(1) 'User' downloads software products or contents from 'Center' or 'Home
Page', which are disabled when downloaded.
(2) Then 'User' requests registration or I icense for the products or contents.
(3) At this timing, media-unique information is generated with the present
invention, such as a DLL supplied by manufacturer.
(4) Now, software products or contents are enabled.
Thirdly, by using this method to write additional media-unique
information, say as TRACKOO.CDA, when music or images are written on CD-ROM,
only legal Iy obtained me iacan be used w i le prohibiting i I legal reproduction
to be made. (Actually, reproduction can be made, but since media-unique
information is differnt from CD-ROM to CD-ROM, copied information will be
considered inval id by players which would implement the present invention.)
In this case, the standard pertaining to the CD-ROM format and the devices
to play the contents on CD-ROM may be affected. An example fol lows: (1) 'Manufacturer' rites media-unique information on CD-ROM with the present
invention as TRACKOO.CDA along with the contents.
(2) 'User"s player checks if TRACKOO.CDA contains valid information.
(3) If so, the contents (music, images, etc) can be played (legal CD-ROM).
Otherwise, the contents can not be played (illegal CD-ROM).
Industrial Applicability
The present invention of applying the fractal encoding methods for
protecting vital information/commercial products from illegal
usage/reproduction can be appI ied to user authentication, electronic banking,
electronic commerce, and software products/contents distribution over a
network, e.g., Internet. It can also be appI ied to authentication of contents
written on CD-ROM such as music and images.

Claims

1. A new method for protecting vi taI information such as password,
PIN, or credit card number transferred over a network by using any fractal
theory-based undecipherable encoding method on both ends (sender and
recipient).
2. A new method for prohibiting i I legal reproduction of software
products or contents distributed over a network by using any fractal
theory-based undecipherable encoding method on recipient side to write
media-unique information on the media where software products or contents are
instaI led (downloaded) upon registration or I icense provision. This encoding
method wi 11 be provided by sel lers of software products or contents along with
software products or contents when downloaded.
3. A new method for prohibiting i I legal reproduction of contents
on CD-ROM such as music or images by using any fractal theory-based
undecipherabIe encoding method to write media-unique information on the media
upon production. This wi 11 involve the alteration to the standard pertaining
to the CD-ROM format and the devices to play the contents on CD-ROM to handle
this additional information.
