A method for managing a networked secure collaborative computer data exchange environment, the method comprising: establishing, by a secure exchange server controlled by an intermediate business entity, a client login data authentication procedure that allows at least one client computing device of a plurality of client computing devices operated by users of a plurality of business entities to access the secure exchange server, wherein communications between the secure exchange server and the plurality of client computing devices is through a communications network; storing, by the secure exchange server, at least one client login authentication data for each of the plurality of client computing devices; receiving content from a first of the plurality of client computing devices; by the secure exchange server, permitting access to the content for a subset of the plurality of computing devices through an exchange content access facility, wherein the exchange content access facility is managed by at least one business entity of the plurality of business entities; granting, by the exchange server, access to the received content to a second of the plurality of client computing devices when the secure exchange server receives from the second of the plurality of client computing devices its client login authentication data provided that the second of the plurality of client computing devices is one of the subset of the plurality of computing devices; providing an amendment voting facility for conducting a process of voting when the content relates to a proposed amendment to an agreement wherein the amendment voting facility enables users of the subset of the plurality of computing devices to vote on the proposed amendment; and providing an electronic signature facility for managing a process of signing the received content by at least one of the subset of the plurality of computing devices, characterized by the electronic signature facility providing for secure viewing of the received content as presented to a signing user through a computer display of the signing user's client computing device, wherein the user's client computing device utilizes a camera for viewing the environment around the signing user and a face detection facility for recognizing the signing user, detecting whether the signing user is the only individual present in the viewed environment and the electronic signature facility implements secure viewing security measures for the received content dependent thereon. establishing, by a secure exchange server controlled by an intermediate business entity, a client login data authentication procedure that allows at least one client computing device of a plurality of client computing devices operated by users of a plurality of business entities to access the secure exchange server, wherein communications between the secure exchange server and the plurality of client computing devices is through a communications network; storing, by the secure exchange server, at least one client login authentication data for each of the plurality of client computing devices; receiving content from a first of the plurality of client computing devices; by the secure exchange server, permitting access to the content for a subset of the plurality of computing devices through an exchange content access facility, wherein the exchange content access facility is managed by at least one business entity of the plurality of business entities; granting, by the exchange server, access to the received content to a second of the plurality of client computing devices when the secure exchange server receives from the second of the plurality of client computing devices its client login authentication data provided that the second of the plurality of client computing devices is one of the subset of the plurality of computing devices; providing an amendment voting facility for conducting a process of voting when the content relates to a proposed amendment to an agreement wherein the amendment voting facility enables users of the subset of the plurality of computing devices to vote on the proposed amendment; and providing an electronic signature facility for managing a process of signing the received content by at least one of the subset of the plurality of computing devices, characterized by the electronic signature facility providing for secure viewing of the received content as presented to a signing user through a computer display of the signing user's client computing device, wherein the user's client computing device utilizes a camera for viewing the environment around the signing user and a face detection facility for recognizing the signing user, detecting whether the signing user is the only individual present in the viewed environment and the electronic signature facility implements secure viewing security measures for the received content dependent thereon.
