## Title
Method for controlling the opening and transmission of electronic data on electronic communication devices

## Abstract

A method is provided for controlling the opening of the representation of electronic data on mobile electronic communication devices, whereby the access to data occurs depending on opening characters which can arise interactively on the same or different mobile communication terminals. Data access thus can be modeled according to a set of rules, corresponding to the usual handling of physical, concrete collectable and exchangeable objects or to the behavior of the natural population.

## Background
BACKGROUND OF THE INVENTION
The present invention relates to a method for opening and transmission of electronic data on electronic communication devices, especially mobile communication terminals. Conventional methods for control of the opening of the presentation of electronic data on electronic communication devices consist of the presentation of electronic data on these types of devices being initiated by a user input.
Electronic communication devices are understood as stationary devices, such as PCs and mobile devices, with mobile electronic communication devices being identified in this context as all electronic devices which are portable in the widest sense and are equipped with facilities for data transmission (mobile telephones, palmtops, or similar). Electronic data can be presented visually and/or audibly. To this end, the electronic communication devices include presentation facilities, if necessary in the form of add-on units. Electronic data to be presented is available in the form of data records. As well as its “content,” a data record contains a record identifier to identify it.
Access to a data record (i.e., the opening of the presentation of the data record on a user instruction), can also depend on an opening code (cf. Table 1). Access is either granted or refused to a data record D1 on a device G1 depending on an opening code.
If electronic data is transmitted, such as in form of visiting cards, e-mail or file transfer, the data is copied from a send device to a receive device.
Transferred data basically can be presented at regular intervals on the sender's as well as the recipient's device. No precautions are taken for the fact that access to a data record on one device may restrict or influence access to a data record on another device and cuts it down in this way. In particular, for the access to transferred data originating from the receiver side, there is no way of influencing which access to the transferred data remains on the send side after the transmission.
The consequence of the almost inherent production of copies during data transmission and the data duplication which follows from this is that digital data is not cut back and can develop into interesting and high-value group objects which can be exchanged between private individuals and similar interests (“collectors”) and also could be the object of commercial exchanges. In particular, therefore, there is no support for processes in the exchange of electronic data which correspond to dealing with physically concrete collective or exchange objects and can be subject to certain rules.
An object of the present invention is, therefore, to overcome the disadvantages mentioned and provide a method for control of the opening of the presentation of electronic data on electronic communication devices, especially mobile electronic communication terminals.
SUMMARY OF THE INVENTION
In a method according to the present invention, for control of the opening of the presentation of electronic data on electronic communication devices, the electronic data is present in the form of data records identified by a record identifier in each case and the presentation of an electronic data record on an electronic communication device is opened depending on an opening code, with a change of a first opening code relating to the presentation of a first electronic record being dependent on a second opening code relating to the presentation of a second electronic record.
The method in accordance with the present invention is preferably used in mobile communication devices.
In an advantageous embodiment, the presentation of the electronic data is opened on electronic communication devices by modeling based on the opening code according to a set of rules which corresponds to the normal way of handling physically concrete group or exchange objects or to the behavior of natural populations.
Additional features and advantages of the present invention are described in, and will be apparent from, the following Detailed Description of the Invention.



BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 shows a flow chart of an embodiment of a method for opening and transmission of electronic data on electronic communication devices.



DETAILED DESCRIPTION OF THE INVENTION
Table 1 shows the modeling of an access to a data record D1. If the opening code is set (Yes), device G1 has access to data record D1. If, on the other hand, the opening code is not set (No), access by device G1 to data record D1 is refused.
Table 2 shows how, for example the transfer of a data record D1 from a device G1 to a device G2 can be modeled Before the transfer, there is access to D1 at G1 but not at G2. After the transfer the situation is reversed. The change of the opening code on G2 and G1 occurs conversely.
Table 3 shows how, by combining two transfer processes, an exchange between a data record D1 on device G1 and a data record D2 on a device G2 can be modeled. Before the exchange, there is access at G1 to D1, but not to D2. At G2 there is access to D2, but not to D1. After the exchange the situation is reversed. The change of the opening codes on G2 and G1 is in the opposite direction here too.
In another—development, similar to processes with natural—populations, a “mutation” of a data record D1 into a data record D2 on the same device can be modeled by changing the opening code of D1 from “Yes” before to “No” afterwards and changing the opening code of D2 in the opposite direction.
In another development, a “propagation” of a data record D1 from a device G1 to a device G2 can be modeled by synchronizing the opening code from D1 to G2 to the opening code from D1 to G1. This can be used to propagate both access and non-access from G1 to G2.
In a further development of this, a “pairing” can be modeled by access to two data records (“parents”) opening access to a third data record (“child”).
In another development, a “pinning on” of a data record D1 on a device G1 to a data record D2 can be modeled by synchronizing the opening code of D1 on G1 to the opening code of D2 on G1.
In another development, the “birth” or “death” of a data record D1 using “timing” can be modeled by switching the opening code of D1 to access or non-access depending on a control signal which is initiated depending on a time measurement.
In another development, random changes of access to a data record D1 on a device G1 can be modeled by making the opening code of D1 on G1 dependent on a (dummy) random algorithm.
In another development, a combined selection can be made from the existing rules.
In another development, the opening codes are modeled by a parameter set; for example, integer, non-negative numbers, etc. Access to a data record (i.e., opening the presentation in response to a user input), is dependent on whether the opening code of the data record falls within a specified subset of parameters; for example, the quantity W. In this way, a population with multiple instances of data records can be modeled. Modeling of “birth”, “death”, “transfer” and “exchange” is shown in Tables 4a, 4b, 5 and 6.
In another development, the permitted opening codes are modeled by binary characters; e.g., 1=data access, 0=no data access.
In another the information about opening codes is also stored on a server. In this way, it is possible for a user of the server to act as the organizer of games and, for example, to obtain fees for participation from the users of the electronic communication devices.
In a further development of this, the opening code on electronic communication devices also can be influenced from the server. Further rules of play can be implemented in this way.
In another development, data communication between the electronic communication devices, especially the mobile communication devices, is based on one of the standards IrDA, HomeRF, IEEE 802.1 or Bluetooth, for example.
Preferably, the data records to be presented essentially contain pictures and/or soundtracks and/or video clips.
Although the present invention has been described with reference to specific embodiments, those of skill in the art will recognize that changes may be made thereto without departing from the spirit and scope of the present invention as set forth in the hereafter appended claims.
