A computer-implemented method for authenticating a request to access a remote resource includes identifying a request from a first device to access a resource located on a second device. The computer-implemented method further includes retrieving one or more encrypted passwords for authenticating access to the resource from a partition of a vault located on the first device. The computer-implemented method further includes comparing the one or more encrypted passwords retrieved from the partition of the vault located on the first device to one or more designated passwords stored on the second device. The computer-implemented method further includes granting the first device access to the resource located on the second device based, at least in part, on the one or more encrypted passwords retrieved from the partition of the vault located on the first device matching the one or more designated passwords stored on the second device.

Examples of techniques for encoding data in a 2D symbology are disclosed. In one example described herein, a computer-implemented method comprises capturing an image of the 2D symbology. The 2D symbology comprises a series of data symbols representing a binary string. Each of the data symbols comprises a line segment, and each data symbol in the series of data symbols are positioned in an end-to-end orientation starting at a starting indicator designated by a first symbol and ending at an ending indicator designated by a second symbol. The first symbol differs from the second symbol, and the series of data symbols comprise 0-bit symbols represented by a first data symbol and 1-bit symbols represented by a second data symbol. The method further comprises extracting the binary string from the 2D symbology by reading each of the data symbols between the starting indicator and the ending indicator.

Encoding and decoding data in two-dimensional symbology

Examples of techniques for encoding data in a 2D symbology are disclosed. In one example implementation according to aspects of the present disclosure, a computer-implemented method includes assigning a first data symbol representative of a 0-bit and a second data symbol representative of a 1-bit, each of the first data symbol and the second data symbol include a line segment. The method further includes designating a starting indicator and an ending indicator. The method also includes generating, by a processing device, the 2D symbology. The 2D symbology includes a series of data symbols representing a binary string. Each data symbol in the series of data symbols are positioned in an end-to-end orientation starting at the starting indicator and ending at the ending indicator. The series of data symbols include 0-bit symbols represented by the first data symbol and 1-bit symbols represented by the second data symbol.

Examples of techniques for encoding data in a 2D symbology are disclosed. In one example implementation according to aspects of the present disclosure, a computer-implemented comprises assigning a first color representative of a 0-bit and a second color representative of a 1-bit. The method further comprises designating a starting cell pair and an ending cell pair. The method also comprises generating, by a processing device, the 2D symbology. The 2D symbology comprises a series of cells in a cell space starting with the starting cell pair and ending with the ending cell pair. Each cell between the starting cell pair and the ending cell pair corresponds to a bit of a binary string and has a common cell length. The cells corresponding to a 0-bit are colored the first color and the cells corresponding to a 1-bit are colored the second color.

Examples of techniques for encoding data in a 2D symbology are disclosed. In one example implementation according to aspects of the present disclosure, a computer-implemented method for encoding data in a 2D symbology is provided. The method comprises assigning a first indicium representative of a 0-bit and a second indicium representative of a 1-bit, designating a starting indicator, and generating, by a processing device, the 2D symbology including a unit array defining a bit length and a plurality of bit arrays.

The series of data segments and null segments starts with the starting indicator and ends with the ending indicator. The data segments include 0-bit segments of the first color and 1-bit segments of the second color. The null segments are positioned between each of the data segments and are of a third color.

To encode information into a two-dimensional (2D) symbol, a palette is selected to represent data in the 2D symbol, the palette including a set of shape fillers. A Base number system is selected according to the palette. A rule is selected, where the rule determines a manner of reading an encoded form of the data from the 2D symbol. The rule and the data are encoded as a set of shapes, where the shapes in the set of shapes are configured using the palette and arranged into a grid pattern, with or without visible grid lines, to form the 2D symbol. The 2D symbol is output in a size that matches an area.

An additional layer of encoding is provided using conventional one-dimensional ('1-D') bar code symbology. Dark bars of at least 2 heights are used (where the dark bars may be narrow or wide, and may be separated by a space that is narrow or wide) for 2-dimensional ('2-D') encoding. Whereas the width of the dark bars is significant in the 1-D encoding, the height of the dark bars is significant for the 2-D encoding. In one approach, dark bars of a shortest height are used for encoding conventional 1-D data, while dark bars of other heights encode additional data in a 2-D portion of a bar code. In another approach, consecutive dark bars are used in combination, according to a mapping which correlates the various combinations of bar heights to respective characters. The 2-D encoding rules may be proprietary, providing a type of data privacy.

Additional encoding in conventional one-dimensional bar code symbologies

A system for authenticating a serialized commodity is presented. A fixed identification, serial number, and authentication code are received for a serialized commodity to be checked for authenticity. A reference table is searched for an entry that matches the received fixed identification. In response to finding an entry in the reference table that matches the received fixed identification, a fixed identification key is retrieved from the reference table that is associated with the received fixed identification. A recreated authentication code is generated for the serialized commodity using the retrieved fixed identification key, the received fixed identification, and the received serial number. Then, it is determined whether the recreated authentication code matches the received authentication code. In response to determining that the recreated authentication code does match the received authentication code, an authentication code match message is outputted to authenticate the serialized commodity.
