Methods and apparatuses for attribution with custom factor mimicking portfolios

A machine for displaying factor-based performance attribution (pa) results for a set of historical portfolios using a framework that computes the attribution using a set of factor mimicking portfolios (fmps). By considering different constraints, universes, and rebalance frequencies for the fmps, different pa results may be obtained. ... Axioma Inc

Methods and apparatus employing hierarchical conditional variance to minimize downside risk of a multi-asset class portfolio and improved graphical user interface

The traditional markowitz mean-variance-optimization (mvo) framework that uses the standard deviation of the possible portfolio returns as a measure of risk does not accurately measure the risk of multi-asset class portfolios whose return distributions are non-gaussian and asymmetric. A scenario-based conditional value-at-risk (cvar) approach for minimizing the downside risk of a multi-asset class portfolio is addressed that uses monte-carlo simulations to generate the asset return scenarios. ...

Fine-grained database access-control policy enforcement using reverse queries

A method of providing access control to a database accessible from a user interface is implemented at a policy enforcement point, which is located between the database and the user interface and includes the steps of: (i) intercepting a database query; (ii) assigning attribute values on the basis of a target table or target column in the query, a construct type in the query, or the user or environment; (iii) partially evaluating an access-control policy defined in terms of said attributes, by constructing a partial policy decision request containing the attribute values assigned in step ii) and evaluating the access-control policy for this, whereby a simplified policy is obtained; (iv) deriving an access condition, for which the simplified policy permits access; and (v) amending the database query by imposing said access condition and transmitting the amended query to the database.. . ...

System and method for evaluating a reverse query

Real-time techniques for determining all access requests to an attribute-based access control policy which evaluate to a given decision, “permit” or “deny”. The policy is enforced to control access to one or more resources in a computer network. ... Axioma Inc

Provisioning system-level permissions using attribute-based access control policies

A permissions provisioning module includes a data adapter and a permissions calculator associated with a policy evaluator operable to evaluate an abac policy. The module is adapted to interact with a computer system including resources, metadata and an access control mechanism enforcing, in respect of each resource, an access control list associated with the resource. ...
