Data security by their transfer on communication channels (it is especially actual when using open communication channels, for example the Internet network). Here use of "a digital digital signature" and other cryptographic methods is possible.

Thus, today it is possible to speak about gradual integration of powerful professional tools of receiving a financial with the Internet technologies. It is possible to claim with confidence that Internet potential as the environment of a of financial data is rather great, and through certain time it is possible to expect universal use of this network in professional activity.

Archives of financial, legal and other which can be used for the analysis. For example: quotations, exchange rates, information on activity of the companies, etc.

Around the world, especially in the USA, it is now active ­ the specialized service suggesting to to be connected to a flow of professional financial information for the insignificant sum. In general, the set of services of financial servers can be subdivided into the following groups:

The system imposes strict requirements to reliability of all its component. In case of creation of own telecommunication system, as a rule, it is necessary to reserve all elements of system: telephone lines, computers, and the telecommunication equipment that naturally increases its cost.

Various restrictions of opportunities of information processing with standard accessors (there are some solutions of this problem. One of them is already widespread in the world and the, using the Internet standards, another with use of the Java programming language developed by the Sun Microsystems company for use in the environment of Internet consists in a specialized program).

Now group of support ­ the standard on means of ensuring of safety in Internet IPSec (Internet Protocol Security). The first suppliers of firewalls and stacks of TCP/IP have to provide compatibility with IPSec.

the organization of access to systems of through various communication channels and protocols - lines (local, long-distance, "Spark", sotova, networks of switching of X.25 packages ("Sprint", "Infotel" or "Rosnet"), IP networks (Relcom or Internet);

High cost of rent of communication channels. It must be kept in mind that usually at the organization of communication with remote offices the switched telephone channels are practically not used. Here high-speed and reliable communication lines are necessary.

If document flow through system in client part is too great for processing by one person, delivery of the special network version of system is possible. In that case the documents passing through system are processed by at the same time many operators, thus different users of system can have different powers during the work with it. The system works in the Novell NetWare and Microsoft NetWorks networks.

As a result at implementation of the project there were the uniform structured cable network for a of data and a telephony with lifelong on its components; the switched and Ethernet and FDDI lines; technologies of communications (resilient links) and the duplicated of servers; systems of duplication of food, up to power supply of the simplest concentrators that ensures trouble-free operation of system even in an emergency.

The system provides two types of service for subscribers: "service according to the schedule" (transmission of messages in the off-line mode) and "service on demand" for transfer of short messages on channels of telecommunication networks.

Sometimes standard means of Internet and, in, WWW do not satisfy service providers of information systems. In a case the specialized and client software, the TCP/IP protocol and standard data links, but providing own user interface and a set of analytical tools (Reuters) is developed.

Now it is possible to meet use examples practically of any of communication. Among the main technological decisions it should be noted: the switched telephone communication lines (including Spark-2 system and cell phones), the X.25 networks ("Sprint", "Infotel" etc.), IP networks (Relcom Internet), satellite communication lines (for example, the of SkyLink of Livewire Digital firm working ­ system of Inmarsat satellites).
